``, ``, ``, ``,
`` and ``
232, 233)
- [makeotfexe] Fixed parsing of Character Variant (cvXX) feature
- [pip] Fixed `pip uninstall afdko`



The **afdko** has been restructured so that it can be installed as a
Python package. It now depends on the user's Python interpreter, and no
longer contains its own Python interpreter.

In order to do this, the two Adobe-owned, non-opensource programs were
dropped: `IS` and `checkOutlines`. If these turn out to be sorely
missed, an installer for them will be added to the old Adobe afdko
website. The current intent is to migrate the many tests in
checkOutlines to the newer `checkOutlinesUFO` (which does work with
OpenType and Type 1 fonts, but currently does only overlap detection and
removal, and a few basic path checks).

Older releases can be downloaded and installed from the [Adobe's AFDKO
home page](



This only lists the major bug fixes since the last release. For a
complete list see:

- [buildCFF2VF] Add version check for fontTools module: only
starting with version 3.19.0 does fontTools.cffLib build correct
PrivateDict BlueValues when there are master source fonts not at the
ends of the axes.
- [makeotfexe] Support mapping a glyph to several Unicode values.
This can now be done by providing the the UV values as a
comma-separated list in the third field of the GlyphOrderAndAliasDB
file, in the 'uniXXXXX' format.
- [makeotfexe] Fixed a crashing bug that can happen when the
features file contains duplicate class kern pairs. Reported by
Andreas Seidel in email.
- [makeotfexe] Add fatal messages if a feature file 'cvParameters'
block is used in anything other than a Character Variant (cvXX)
feature, or if a 'featureNames' block is used in anything other
than a Stylistic Set (ssXX) feature.
- [makeotfexe] Relaxed restrictions on name table name IDs. Only 2
and 6 are now reserved for the implementation.
- [makeotfexe] Fixed bug where use of the 'size' feature in
conjunction with named stylistic alternates would cause the last
stylistic alternate name to be replaced by the size feature menu
name. Incidentally removed old patent notices.
- [makeotfexe] Restored old check for the fatal error of two
different glyphs being mapped to the same character encoding.
- [makeotfexe] If the last line of a GOADB file did not end in a
new-line, makeotf quit, saying the line was too long.
- [otf2otc] Can now take a single font as input, and can take an OTC
font as input.
- [sfntdiff] Fixed old bug: it used to crash if no file path or only
one file path was provided.
- [sfntdiff] Changed behavior: it now returns non-zero only if a
real error occurs; it used to return non-zero when there was a
difference between the fonts.
- [spot] Fixed old bug: a PrivateDict must exist, but it is legal
for it to have a length of 0.
- [tx *et al.*] Add support for reading and writing blended hints
from/to CFF2.



- [makeInstancesUFO] Preserve public.postscriptNames lib key.
- [makeInstancesUFO] Do not use postscriptFontName attribute.
- [makeotf] New option -V to print script version.
- [tx] Added new option '-maxs', to set the maximum number of
subroutines allowed. The default is now 32K, as some legacy systems
cannot support more than this.
- [tx] Add improved CFF2 support: tx can now use the option -cff2 to
write from a CFF2 font (in a complete OpenType font) to a file
containing the output CFF2 table, with full charstring optimization
and subroutinization. This last option is still work in progress: it
has not been extensively tested, and does yet support blended hints.
- [tx] Several bug fixes for overlap removal.
- [tx] Fixed bug in subroutinization that could leave a small number
of unused subroutines in the font. This cleanup is optional, as it
requires 3x the processing speed with the option than without, and
typically reduces the font size by less than 0.5 percent.
- [ttxn] Option '-nv' will now print name IDs 3 and 5, but with
the actual version number replaced by the string "VERSION
- [ufoTools] FIx autohint bug with UFO fonts: if edit a glyph and
re-hint, autohint uses old processed layer glyph.



- [variable fonts] **buildMasterOTFs** new script to build OTF font
files from UFO sources, when building variable fonts.
- [variable fonts] **buildCFF2VF** new command to build a CFF2
variable font from the master OTF fonts.
- [autohint] Fixed bug introduced by typo on Dec 1 2015. Caused
BlueFuzz to always be set to 1. Rarely causes problems, but found it
with font that sets BlueFuzz to zero; with BlueFuzz set to 1, some
of the alignment zones were filtered out as being closer than
- [autohint] Fixed long-standing bug with UFO fonts where if a glyph
was edited after being hinted, running autohint would process and
output only the old version of the glyph from the processed layer.
- [CheckOutlinesUFO] Added "quiet mode" option.
- [CheckOutlinesUFO] Fixed a bug where logic could try and set an
off-curve point as a start point.
- [CheckOutlinesUFO] Changed the logic for assigning contour order
and start point. The overlap removal changes both, and
checkOutlinesUFO makes some attempt to restore the original state
when possible. These changes will result in different contour order
and start points than before the change, but fixes a bug, and will
usually produce the same contour order and start point in fonts that
are generated as instances from a set of master designs. There will
always be cases where there will be some differences.
- [MakeOTF] Replace old logic for deriving relative paths with
python function for the same.
- [MakeOTF] When converting Type 1 to CID in makeotf, the logic in
mergeFonts and was requiring the FDArray
FontDicts to have keys, like FullName, that are not in fact
required, and are often not present in the source fonts. Fixed both
mergeFonts and
- [MakeOTF] By default, makeotf will add a minimal stub DSIG table
in release mode. The new options '-addDSIG' and '-omitDSIG' will
force makeotf to either add or omit the stub DSIG table. This
function was added because the Adobe Type group is discontinuing
signing font files.
- [makeotfexe] Fixed bug in processing UVS input file for makeotf
for non-CID fonts.
- [makeotfexe] Fixed bug where makeotf would reject a nameID 25
record when specified in a feature file. This nameID value used to
be reserved, but is now used for overriding the postscript family
named used with arbitrary instances in variable fonts.
- [mergeFonts] Removed requirement for mergeFonts that each FontDict
have a FullName, Weight, and Family Name. This fixes a bug in using
mergeFonts with UFO sources and converting to CID-keyed output font.
Developers should not have to put these fields in the source fonts,
since they are not required.
- [spot] Fixed bug in name table dump: Microsoft platform language
tags for Big5 and PRC were swapped.
- [stemHist] Removed debug print line, that caused a lot of annoying
output, and was left in the last update by accident.
- [tx] When getting Unicode values for output, the presence of UVS
cmap meant that no UV values were read from any other cmap subtable.
I fixed this bug, but 'tx' still does not support reading and
showing UVS values. Doing so will be a significant amount of work,
so I am deferring that to my next round of FDK work.
- [tx] Added support for CFF2 variable fonts as source fonts: when
using -t1 or -cff, these will be snapshotted to an instance. If no
user design vector (UDV) argument is supplied, then the output will
be the default data. If a UDV argument is supplied with the option
-U, then the instance is built at the specified point in the design
- [tx] Added new option +V/-V to remove overlaps in output Type 1
fonts (mode -t1) and CFF fonts (mode -cff). This is still
- [tx] Made the subroutinizer a lot faster; the speed bump is quite
noticeable with CJK fonts. (by Ariza Michiharu)
- [tx] Added new option (+V/-V) to remove overlaps. (by Ariza
- [ttx] Updated to version 3.9.1 of the fontTools module from master
branch on GitHub.



- [CMAP files] Updated UniCNS-UTF32-H to v1.14
- [build] Made changes to allow compiling under Xcode 7.x and OSX
- [documentation] Fixed a bunch of errors in the Feature File spec.
My thanks to Sascha Brawer, who has been reviewing it carefully. See
the issues at
- [autohint] Fixed support for history file, which can be used with
non-UFO fonts only. This has been broken since UFO support was
- [autohintexe] Fixed really old bug: ascenders and descenders get
dropped from the alignment zone report if they are a) not in an
alignment zone and b) there is an overlapping smaller stem hint.
This happened with a lot of descenders.
- [checkOutlines] Fixed bug in that kept checkOutlines
(NOT checkOutlinesUFO) from working with a UFO font.
- [checkOutlines] Fixed bug which misidentified orientation of path
which is very thin and in part convex. I am a bit concerned about
the solution, as what I did was to delete some logic that was used
to double-check the default rules for determining orientation.
However, the default logic is the standard way to determine
orientation and should always be correct. The backup logic was
definitely not always correct as it was applied only to a single
point, and was correct only if the curve associated with the point
is concave. It is in fact applied at several different points on a
path, with the majority vote winning. Since the backup logic is used
only when a path is very thin, I suspect that it was a sloppy
solution to fix a specific case. The change was tested with several
large fonts, and found no false positives.
- [makeInstances] Fixed bug which produced distorted shapes for
those glyphs which were written with the Type 1 'seac' operator,
a.k.a. Type 1 composite glyphs.
- [makeotfexe] Fixed bug where using both kern format A and B in a
single lookup caused random values to be assigned.
- [makeotfexe] Fixed bug where a format A kern value (a single
value) would be applied to X positioning rather than Y positioning
for the features 'vkrn'. Applied same logic to vpal, valt, and
- [makeotfexe] Finally integrated Georg Seifert's code for
supporting hyphen in development glyph names. This version differs
from Georg's branch in that it does not allow any of the special
characters in final names (i.e. the left side names in the
GlyphAliasAndOrderDB). However, allowing this is a smaller tweak
than it used to be: just use the same arguments in
`cb.c:gnameFinalScan()` as in `gnameDevScan()`. This update also
includes Georg's changes for allow source fonts to have CID names
in the form 'cidNNNN'.
- [ConvertToCID] Fixed bug that the script expected in several
places that the fontinfo file would contain at least one user
defined FontDict.
- [ConvertToCID] Fixed bug that the script expected that the source
font would have Weight and Adobe Copyright fields in the font dict.
- [makeotf] Fixed a bug that kept the '-nS' option for having any
effect when the '-cn' option is used.
- [makeotfexe] Remove use of 'strsep()'; function is not defined
in the Windows C library.
- [makeotf] Fixed bug in removing duplicate and conflicting entries.
Changed logic to leave the first pair defined out of a set of
duplicate or conflicting entries.
- [makeotfexe] Fixed bug in processing GDEF glyph class statements:
if multiple GlyphClass statements were used; the additional glyphs
were added to a new set of 4 glyph classes, rather than merged with
the allowed 4 glyph classes.
- [makeotfexe] Fixed issue in GDEF definition processing. Made it an
error to specify both LigCaretByPosition and LigCaretByIndex for a
- [makeotfexe] Corrected error message: language and system
statements are allowed in named lookups within a feature definition,
but are not allowed in stand-alone lookups.
- [makeotf] Corrected typo in help text about what the
default source font path.
- [makeotfexe] Fixed an old bug in makeotf. If a mark-to-base or
mark-to-mark lookup has statements that do not all reference the
same mark classes, makeotfexe used to write a 'default' anchor
attachment point of (0.0) for any mark class that was not referenced
by a given statement. Fixed this bug by reporting a fatal error: the
feature file must be re-written so that all the statements in a
lookup must all reference the same set of mark classes.
- [makeotf] Suppressed warning about not using GOADB file when
building a CID font. Some of the changes I made a few weeks ago to
allow building fonts with CIDs specified as glyphs names with the
form 'cidNNNNN' allowed this warning to be be shown, but it is not
appropriate for CID-keyed fonts.
- [makeotf] Fixed old bug where using option -'cn' to convert a
non-CID source font to CID would cause a mismatch between the maxp
table number of glyphs and the number of glyph actually in the output
font, because the conversion used the source font data rather than
the first pass name-keyed OTF which had been subject to glyph
subsetting with the GOADB file.
- [makeotf] Fixed bug in reading UVS files for non\_CID fonts.
- Fixed copyright statements that are incompatible with the open
source license. Thanks to Dmitry Smirnov for pointing these out.
These were in some make files, an example Adobe CMAP file, and some
of the technical documentation.
- Fixed typos in help text in Thank you Arno Enslin.
- [ttxn] Fixed bug in that broke it when dumping some
tables, when used with latest fontTools library.
- [tx] Fixed bug in rounding fractional values when flattening
library elements, used in design of CJK fonts.
- [tx] Fixed bug in handling FontDict FontMatrix array values: not
enough precision was used, so that 1/2048 was written as 1/2049 in
some cases.
- [tx] Fixed bug in reading UFO fonts, so that glyphs with no
`<outline>` element and with a `<lib>` element would be skipped.
- [tx] Minor code changes to allow 'tx' to compile as a 64 bit
- [tx] Fixed bug in dumping AFM format data, introduced when tx was
updated to be 64 bit.
- [tx] Fixed bug in processing seac, introduced in work on rounding
fractional values.
- [tx] Fixed bug in writing AFM files: -1 value would be written as
4294967295 instead of -1.
- [tx] Added option -noOpt, renamed blend operator from 'reserved'
to 'blend'. This was done in order to support experiments with
multiple master fonts.
- [tx] When reading a UFO font: if it has no Postscript version
entry, set the version to 1.0.
- [tx] When writing a UFO font: if StemSnap[H,V] are missing, but
Std[H,V]W are present, use the Std[H,V]W values to supply the
UFO's postscript StemSnap[H,V] values.
- [tx] Fixed old bug with rounding decimal values for BlueScale is
one of the few Postscript values with several places of decimal
precision. It is stored as an ASCII text decimal point number in T1,
T2, and UFO files, but is stored internally as a C 'float' value
in some programs. Real values in C cannot exactly represent all
decimal values. For example, the closest that a C 'float' value
can come to "0.375" is "0.03750000149".When writing output
fonts, tx was writing out the latter value in ASCII text, rather
than rounding back to 0.0375. Fixed by rounding to 8 decimal places
on writing the value out. This bug had no practical consequences, as
0.0375 and 0.03750000149 both convert to exactly the same float
value, but was annoying, and could cause rounding differences in any
programs that use higher precision fields to hold the BlueScale



- [makeotf] Fixed bug that kept makeotfexe from building fonts with
spaces in the path.
- [ConvertFontToCID] Fixed bug that kept makeotf from converting UFO
fonts to CID.
- [makeotf] Changed support for Unicode Variation Sequence file
(option '-ci') so that when used with name-keyed fonts, the
Region-Order field is omitted, and the glyph name may be either a
final name or developer glyph name. Added warning when glyph in the
UVS entry is not found in font. See MakeOTF User's Guide.
- [makeotfexe] now always makes a cmap table subtable MS platform,
Unicode, format 4 for CID fonts. This is required by Windows. If
there are no BMP Unicode values, then it makes a stub subtable,
mapping GID 0 to UVS 0.
- [tx *et al.*] When reading a UFO source font, do not complain if
the fontinfo.plist entry `styleName` is present but has an empty
string. This is valid, and is common when the style is **Regular**.



- [autohint/tx] Switched to using new text format that is
plist-compatible for T1 hint data in UFO fonts. See header of for format.
- [autohint] Finally fixed excessive generation of flex hints. This
has been an issue for decades, but never got fixed because it did
not show up anywhere as a problem. The last version of makeotf
turned on parsing warnings, and so now we notice.
- [checkOutlinesUFO] Fixed bug where abutting paths did not get
merged if there were no changes in the set of points.
- [checkOutlinesUFO] Fixed bug where a `.glif` file without an
`<outline>` element was treated as fatal error. It is valid for the
`<outline>` element to be missing.
- [checkOutlines] Changed -I option so that it also turns off
checking for tiny paths. Added new option -5 to turn this check back
on again.
- [checkOutlinesUFO] Increased max number of paths in a glyph from
64 to 128, per request from a developer.
- [CompareFamily] Fixed old bug in applying ligature width tests for
CID fonts, and fixed issue with fonts that do not have Mac name
table names. The logic now reports missing Mac name table names only
if there actually are some: if there are none, these messages are
- [fontplot/waterfallplot/hintplot/fontsetplot] Fixed bugs that
prevented these from being used with CID-keyed fonts and UFO fonts.
Since the third party library that generates the PDF files is very
limited, I did this by simply converting the source files to a
name-keyed Type 1 temporary font file, and then applying the tools
the temporary file.
- [makeInstancesUFO] Added a call to the ufonormalizer tool for each
instance. Also added a call to the defcon library to remove all
private lib keys from and each glyph in the default layer,
excepting only "public.glyphOrder".
- Fixed typos in MakeOTF User Guide reported by Gustavo Ferreira
- [MakeOTF] Increased max number of directories to look upwards when
searching for GOADB and FontMenuNameDB files from 2 to 3.
- [MakeOTF/makeotfexe] Added three new options:

- `omitMacNames` and `useMacNames` write only Windows platform
menu names in name table, apart from the names specified in
the feature file. `useMacNames` writes Mac as well as
Windows names.
- `overrideMenuNames` allows feature file name table entries
to override default values and the values from the
FontMenuNameDB for name IDs. NameIDs 2 and 6 cannot be
overridden. Use this with caution, and make sure you have
provided feature file name table entries for all platforms.
- `skco`/`nskco` do/do not suppress kern class optimization by
using left side class 0 for non-zero kern values. Optimizing
saves a few hundred to thousand bytes, but confuses some
programs. Optimizing is the default behavior, and previously
was the only option.

- [MakeOTF] Allow building an OTF from a UFO font only. The internal
`features.fea` file will be used if there is no `features` file in
the font's parent directory. If the GlyphAliasAndOrderDB file is
missing, only a warning will be issued. If the FontMenuNameDB is
missing, makeotf will attempt to build the font menu names from the
UFO fontinfo file, using the first of the following keys found:
`openTypeNamePreferredFamilyName`, `familyName`, the family name
part of the `postScriptName`, and finally the value
**NoFamilyName**. For style, the keys are:
`openTypeNamePreferredSubfamilyName`, `styleName`, the style name
part of the `postScriptName`, and finally the value **Regular**.
- [MakeOTF] Fixed bug where it allowed the input and output file
paths to be the same.
- [makeotfexe] Extended the set of characters allowed in glyph names
to include `+ * : ~ ^ !`.
- [makeotfexe] Allow developer glyph names to start with numbers;
final names must still follow the PS spec.
- [makeotfexe] Fixed crashing bug with more than 32K glyphs in a
name-keyed font, reported by Gustavo Ferreira.
- [makeotfexe] Merged changes from Khaled Hosny, to remove
requirement that 'size' feature menu names have Mac platform
- [makeotfexe] Code maintenance in generation of the feature file
parser. Rebuilt the 'antler' parser generator to get rid of a
compile-time warning for zzerraction, and changed featgram.g so that
it would generate the current featgram.c, rather than having to edit
the latter directly. Deleted the object files for the 'antler'
parser generator, and updated the read-me for the parser generator.
- [makeotfexe] Fixed really old bug: relative include file
references in feature files have not worked right since the FDK
moved from Mac OS 9 to OSX. They are now relative to the parent
directory of the including feature file. If that is not found, then
makeotf tries to apply the reference as relative to the main feature
- [spot] Fixed bug in dumping stylistic feature names.
- [spot] Fixed bug proofing vertical features: needed to use vkern
values. Fix contributed by Hiroki Kanou.
- [tx *et all.*] Fix crash when using '-gx' option with source UFO
- [tx *et all.*] Fix crash when a UFO glyph point has a name
attribute with an empty string.
- [tx *et all.*] Fix crash when a UFO font has no public.glyphOrder
dict in the lib.plist file.
- [tx *et all.*] Fix really old bug in reading TTF fonts, reported
by Belleve Invis. TrueType glyphs with nested component references
and x/y offsets or translation get shifted.
- [tx *et all.*] Added new option '-fdx' to select glyphs by
excluding all glyphs with the specified FDArray indices. This and
the '-fd' option now take lists and ranges of indices, as well as
a single index value.
- Added a command to call the ufonormalizer tool.
- Updated to latest version of booleanOperatons, defcon (ufo3 branch),
fontMath (ufo3 branch), fontTools, mutatorMath, and robofab (ufo3
branch). The AFDKO no longer contains any private branches of third
party modules.
- Rebuilt the Mac OSX, Linux and Windows Python interpreters in the
AFDKO, bringing the Python version up to 2.7.10. The Python
interpreters are now built for 64-bit systems, and will not run on
32-bit systems.



- [ufoTools] Fixed bug that was harmless but annoying. Every time
that `autohint -all` was run, it added a new program name entry to
the history list in the hashmap for each processed glyph. You saw
this only if you opened the hashmap file with a text editor, and
perhaps eventually in slightly slower performance.
- [checkOutlinesUFO] Fixed bug where presence of outlines with only
one or two points caused a stack dump.
- [makeotf] Fixed bug reported by Paul van der Laan: failed to build
TTF file when the output file name contains spaces.
- [spot] Fixed new bug that caused spot to crash when dumping GPOS
'size' feature in feature file format.



- [ufoTools] Fixed bug which placed a new hint block after a flex
operator, when it should be before.
- [autohint] Fixed new bug in hinting non-UFO fonts, introduced by
the switch to absolute coordinates in the bez file interchange
- [ufoTools] Fixed bugs in using hashmap to detect previously hinted
- [ufoTools] Fixed bugs in handling the issue that (which uses the defcon library to write UFO glif
files) will in some cases write glif files with different file names
than they had in the default glyph layer.
- [makeotf] Fixed bug with Unicode values in the absolute path to to
the font home directory.
- [makeotf] Add support for Character Variant (cvXX) feature params.
- [makeotf] Fixed bug where setting Italic style forced OS/2 version
to be 4.
- [spot] Added support for cvXX feature params.
- [spot] Fixed in crash in dumping long contextual substitution
strings, such as in 'GentiumPlus-R.TTF'.
- [tx] Fixed bug in handling CID glyph ID greater than 32K.
- [tx] Changed to write widths and FontBBox as integer values.
- [tx] Changed to write SVG, UFO, and dump coordinates with 2 places
of precision when there is a fractional part.
- [tx] Fixed bugs in handling the '-gx' option to exclude glyphs.
Fixed problem with CID \> 32K. Fixed problem when font has 65536
glyphs: all glyphs after first last would be excluded.
- [tx] Fixed rounding errors in writing out decimal values to cff
and t1 fonts.
- [tx] Increased interpreter stack depth to allow for CUBE operators
(Library elements) with up to 9 blend axes.
- Fixed Windows builds: had to provide a roundf() function, and more
includes for the \_tmpFile function. Fixed a few compile errors.
- Fixed bug in documentation for makeInstancesUFO.
- Fixed bug in on Windows, when having to use a temp file.



- [autohintexe] Worked through a lot of problems with fractional
coordinates. In the previous release, autohintexe was changed to
read and write fractional values. However, internal value storage
used a Fixed format with only 7 bits of precision for the value.
This meant that underflow errors occurred with 2 decimal places,
leading to incorrect coordinates. I was able to fix this by changing
the code to use 8 bits of precision, which supports 2 decimal places
(but not more!) without rounding errors, but this required many
changes. The current autohint output will match the output of the
previous version for integer input values, with two exceptions.
Fractional stem values will (rarely) differ in the second decimal
place. The new version will also choose different hints in glyphs
which have coordinate values outside of the range -16256 to +16256;
the previous version had a bug in calculating weights for stems.
- [autohint] Changed logic for writing bez files to write absolute
coordinate values instead of relative coordinate values. Fixed bug
where truncation of decimal values lead to cumulative errors in
positions adding up to more than 1 design unit over the length of a
- [tx] Fixed bugs in handling fractional values: `tx` had a bug with
writing fractional values that are very near an integer value for
the modes -dump, -svg, and -ufo. `tx` also always applied the logic
for applying a user transform matrix, even though the default
transform is the identity transform. This has the side-effect of
rounding to integer values.



- [checkOutlinesUFO] Added new logic to delete any glyphs from the
processed layer which are not in the 'glyphs' layer.
- [makeotf] When building CID font, some error messages were printed
- [makeotf] Added new option `stubCmap4`. This causes makeotf to
build only a stub cmap 4 subtable, with just two segments. Needed
only for special cases like AdobeBlank, where every byte is an
issue. Windows requires a cmap format 4 subtable, but not that it be
- [makeCIDFont] Output FontDict was sized incorrectly. A function at
the end adds some FontInfo keys, but did not increment the size of
the dict. Legacy logic is to make the FontInfo dict be 3 larger than
the current number of keys.
- [makeInstanceUFO] Changed AFDKO's branch of mutatorMath so that
kern values, glyph widths, and the BlueValues family of global hint
values are all rounded to integer even when the `decimal` option is
- [makeInstanceUFO] Now deletes the default 'glyphs' layer of the
target instance font before generating the instance. This solves the
problem that when glyphs are removed from the master instances, the
instance font still has them.
- [makeInstanceUFO] Added a new logic to delete any glyphs from the
processed layer which are not in the 'glyphs' layer.
- [makeInstanceUFO] Removed the `all` option: even though
mutatorMath rewrites all the glyphs, the hash values are still valid
for glyphs which have not been edited. This means that if the
developer edits only a few glyphs in the master designs, only those
glyphs in the instances will get processed by checkOutlinesUFO and
- Support fractional coordinate values in UFO workflow:

- checkOutlinesUFO (but not checkOutlines), autohint, and
makeInstancesUFO will now all pass through decimal
coordinates without rounding, if you use the new option
"decimal". tx will dump decimal values with 3 decimal
- tx already reported fractional values, but needed to be
modified to report only 3 decimal places when writing UFO
glif files, and in PDF output mode: Acrobat will not read
PDF files with 9 decimal places in position values.
- This allows a developer to use a much higher precision of
point positioning without using a larger em-square. The
Adobe Type group found that using an em-square of other than
1000 design units still causes problems in layout and text
selection line height in many apps, despite it being legal
by the Type 1 and CFF specifications.
- Note that code design issues in autohint currently limit the
decimal precision and accuracy to 2 decimal places: 1.01
works but 1.001 will be rounded to 0.



- [tx] Fix bug in reading TTFs. Font version was taken from the name
table, which can include a good deal more than just the font
version. Changed to read fontRevision from the head table.
- [detype1] Changed to wrap line only after an operator name, so
that the coordinates for a command and the command name would stay
on one line.
- [otf2otc] Pad table data with zeros so as to align tables on a 4
boundary. Submitted by Cosimo Lupo.



- [ufoTools] Fixed a bug with processing flex hints that caused
outline distortion.
- [compareFamily] Fixed bug in processing hints: it would miss
fractional hints, and so falsely report a glyph as having no hints.
- [compareFamily] Support processing CFF font without a FullName
- [checkOutlinesUFO] Coordinates are written as integers, as well as
being rounded.
- [checkOutlinesUFO] Changed save function so that only the
processed glyph layer is saved, and the default layer is not
- [checkOutlinesUFO] Changed so that XML type is written as
'UTF-8' rather than 'utf-8'. This was actually a change in the
FontTools module.
- [checkOutlinesUFO] Fixed typos in usage and help text.
- [checkOutlinesUFO] Fixed hash dictionary handling so that it will
work with autohint, when skipping already processed glyphs.
- [checkOutlinesUFO] Fixed false report of overlap removal when only
change was removing flat curve
- [checkOutlinesUFO] Fixed stack dump when new glyph is seen which
is not in hash map of previously processed glyphs.
- [checkOutlinesUFO] Added logic to make a reasonable effort to sort
the new glyph contours in the same order as the source glyph
contours, so the final contour order will not depend on (x,y)
position. This was needed because the pyClipper library (which is
used to remove overlaps) otherwise sorts the contours in (x,y)
position order, which can result in different contour order in
different instance fonts from the same set of master fonts.
- [makeInstancesUFO] Changed so that the option -i (selection of
which instances to build) actually works.
- [makeInstancesUFO] Removed dependency on the presence of
instance.txt file.
- [makeInstancesUFO] Changed to call checkOutlinesUFO rather than
- [makeInstancesUFO] Removed hack of converting all file paths to
absolute file paths: this was a work-around for a bug in
robofab-ufo3k that is now fixed.
- [makeInstancesUFO] Removed all references to old instances.txt
meta data file.
- [makeInstancesUFO] Fixed so that current dir does not have to be
the parent dir of the design space file.
- Merged fixes from the GitHub AFDKO open source repo.
- Updated to latest version defcon, fontMath, robofab, and
- Fix for Yosemite (Mac OSX 10.10) in FDK/Tools/setFDKPaths. When an
AFDKO script is ran from another Python interpreter, such as the one
in RoboFont, the parent Python interpreter may set the Unix
environment variables PYTHONHOME and PYTHONPATH. This can cause the
AFDKO Python interpreter to load some modules from its own library,
and others from the parent interpreters library. If these are
incompatible, a crash ensues. The fix is to unset the variables
PYTHONHOME and PYTHONPATH before the AFDKO interpreter is called.
Note: As a separate issue, under Mac OSX 10.10, Python calls to FDK
commands will only work if the calling app is run from the
command-line (e.g: `open /Applications/`), and the
argument `shell="True"` is added to the subprocess module call to
open a system command. I favor also adding the argument
`stderr=subprocess.STDOUT`, else you will not see error messages
from the Unix shell. Example:
`log = subprocess.check_output( "makeotf -u", stderr=subprocess.STDOUT, shell=True)`.



- [spot] Fixed error message in GSUB chain contextual 3 proof file
output; was adding it as a shell comment to the proof output,
causing conversion to PDF to fail.
- [makeotf] Increased the limit for glyph name length from 31 to 63
characters. This is not encouraged in shipping fonts, as there may
be text engines that will not accept glyphs with more than 31
characters. This was done to allow building test fonts to look for
such cases.



- [makeInstancesUFO] Added new script to build instance fonts from
UFO master design fonts. This uses the design space XML file
exported by Superpolator 3 in order to define the design space, and
the location of the masters and instance fonts in the design space.
The definition of the format of this file, and the library to use
the design space file data, is in the open source mutatorMath
library on GitHub, and maintained by Erik van Blokland. There are
several advantages of the Superpolator design space over the
previous **makeInstances** script, which uses the Type 1 Multiple
Master font format to hold the master designs. The new version a)
allows different master designs and locations for each glyph, and b)
allows master designs to be arbitrarily placed in the design space,
and hence allows intermediate masters. In order to use the
mutatorMath library, the AFDKO-supplied Python now contains the
robofab, fontMath, and defcon libraries, as well as mutatorMath.
- [ttx] Updated to the latest branch of the fontTools library as
maintained by Behdad Esfahbod on GitHub. Added a patch to
to fix a minor problem with choosing charset format with large glyph
- Updated four Adobe-CNS1-\* ordering files.



- [makeotf] Now detects `IsOS/2WidthWeightSlopeOnly` as well as the
misspelled `IsOS/2WidthWeigthSlopeOnly`, when processing the
fontinfo file.
- [makeotfexe] Changed behavior when 'subtable' keyword is used in
a lookup other than class kerning. This condition now triggers only
a warning, not a fatal error. Change requested by FontForge
- [makeotf] Fixed bug which prevented making TTF fonts under
Windows. This was a problem in quoting paths used with the 'ttx'
- Fixed installation issues: removed old Windows install files from
the Windows AFDKOPython directory. This was causing installation of
a new AFDKO version under Windows to fail when the user's PATH
environment variable contained the path to the AFDKOPython
directory. Also fixed command file for invoking
- Updated files used for building ideographic fonts with Unicode IVS
`FDK/Tools/SharedData/Adobe Cmaps/Adobe-CNS1/Adobe-CNS1_sequences.txt`
and `Adobe-Korea1_sequences.txt`.



- [IS/addGlobalColor] When using the '-bc' option, fixed bug with
overflow for CID value in dumping glyph header. Fixed bug in IS to
avoid crash when logic for glyphs \> 72 points is used.
- [makeotfexe] Fixed bug that applied '-gs' option as default
behavior, subsetting the source font to the list of glyphs in the



- [makeotf] When building output TTF font from an input TTF font,
will now suppress warnings that hints are missing. Added a new
option '-shw' to suppress these warnings for other fonts that with
unhinted glyphs. These warnings are shown only when the font is
built in release mode.
- [makeotfexe] If the cmap format 4 UTF16 subtable is too large to
write, then makeotfexe writes a stub subtable with just the first
two segments. The last two versions allowed using '-' in glyph
names. Removed this, as it breaks using glyph tag ranges in feature
- Updated copyright, and removed patent references. Made extensive
changes to the source code tree and build process, to make it easier
to build the open source AFDKO. Unfortunately, the source code for
the **IS** and **checkOutlines** programs cannot be open sourced.
- [tx/mergeFonts/rotateFont] Removed '-bc' option support, as
this includes patents that cannot be shared in open source.
- [tx] All tx-related tools now report when a font exceeds the max
allowed subroutine recursion depth.
- [tx/mergeFonts/rotateFont] Added common options to all when
possible: all now support UFO and SVG fonts, the '-gx' option to
exclude fonts, the '-std' option for cff output, and the '-b'
option for cff output.



- [makeotf] Added new option '-gs'. If the '-ga' or '-r'
option is used, then '-gs' will omit from the font any glyphs
which are not named in the GOADB file.
- [Linux] Replaced the previous build (which worked only on 64-bit
systems) with a 32 bit version, and rebuilt checkOutlines with debug
messages turned off.
- [ttx] Fixed FDK/Tools/win/ttx.cmd file so that the 'ttx' command
works again.



- [makeotf] Add support for two new 'features' file keywords, for
the OS/2 table. Specifying 'LowerOpSize' and 'UpperOpSize' now
sets the values 'usLowerOpticalPointSize' and
'usUpperOpticalPointSize' in the OS/2 table, and set the table
version to 5.
- [makeotf] Fixed the '-newNameID4' option so that if the style
name is "Regular", it is omitted for the Windows platform name ID
4, as well as in the Mac platform version. See change in
build 61250.
- [tx] When the user does not specify an output destination file
path (in which case tx tries to write to stdout), tx now reports a
fatal error if the output is a UFO font, rather than crashing.
- [tx] Fixed crash when encountering an empty `<dict/>` XML
- [spot] Added logic to dump the new fields in OS/2 table version 5,
**usLowerOpticalPointSize** and **usUpperOpticalPointSize**. An
example of these values can be seen in the Windows 8 system font
- [ufo workflow] Fixed autohint and checkOutlines so that the '-o'
option works, by copying the source UFO font to the destination UFO
font name, and then running the program on the destination UFO font.
- [ufo workflow] Fixed tools that the PostScript font name is not
- Added Linux build.



- [tx] Fixed rare crashing bug in reading a font file, where a
charstring ends exactly on a refill buffer boundary.
- [tx] Fixed rare crashing bug in subroutinization.
- [tx] Fixed bug where it reported values for wrong glyph with more
than 32K glyphs in the font.
- [tx] Fixed bug where the tool would not dump a TrueType Collection
font file that contained OpenType/CFF fonts.
- [tx] Fixed issue where it failed to read a UFO font if the UFO
font lacked a fontinfo.plist file, or a psFontName entry.
- [IS] Fixed IS so that it no longer scales the fontDict FontMatrix,
when a scale factor is supplied, unless you provide an argument to
request this.
- [makeotf] The option '-newNameID4' now builds both Mac and Win
name ID 4 using name ID 1 and 2, as specified in the OpenType spec.
The style name is omitted from name ID 4 it is "Regular".
- [makeotf] Changed logic for specifying ValueFormat for PosPair
value records. Previous logic always used the minimum ValueFormat.
Since changing ValueFormat between one PosPair record and the next
requires starting a new subtable, feature files that used more than
one position adjustment in a PosPair value record often got more
subtable breaks then necessary, especially when specifying a PairPos
statement with an all zero Value Record value after a PairPos
statement with a non-zero Value Record. With the new logic, if the
minimum ValueFormat for the new ValueRecord is different than the
ValueFormat used with the ValueRecord for the previous PairPos
statement, and the previous ValueFormat permits expressing all the
values in the current ValueRecord, then the previous ValueFormat is
used for the new ValueRecord.
- Added commands **otc2otf** and **otf2otc** to build OpenType
collection files from a OpenType font files, and vice-versa.
- [ttx] Updated the FontTools library to the latest build on the
GitHub branch maintained by Behdad Esfahbod, as of Jan 14 2014.
- [ufo workflow] Fixed bugs in The glyph list was being
returned in alphabetic order, even when the public.glyphOrder key
was present in Failed when the glyphOrder key was missing.



- [tx] Can now take UFO font as a source font file for all outputs
except rasterization. It prefers GLIF file from the layer
``. You can select another
preferred layer with the option '-altLayer `<layer name>`'. Use
'None' for the layer name in order to have tx ignore the preferred
layer and read GLIF files only from the default layer.
- [tx] Can now write to a UFO with the option '-ufo'. Note that it
is NOT a full UFO writer. It writes only the information from the
Postscript font data. If the source is an OTF or TTF font, it will
not copy any of the meta data from outside the font program table.
Also, if the destination is an already existing UFO font, tx will
overwrite it with the new data: it will not merge the new font data
with the old.
- [tx] Fixed bugs with CID values \> 32K: used to write these as
negative numbers when dumping to text formats such as AFM.
- [autohint/checkOutlines] These programs can now be used with UFO
fonts. When the source is a UFO font, the option '-o' to write to
another font is not permitted. The changed GLIF files are written to
the layer ''. Each script
maintains a hash of the width and marking path operators in order to
be able to tell if the glyph data in the default layer has changed
since the script was last run. This allows the scripts to process
only those glyphs which have changed since the last run. The first
run of autohint can take two minutes for a 2000 glyph font; the
second run takes less then a second, as it does not need to process
the unchanged glyphs.
- [stemHist/makeotf] Can now take UFO fonts as source fonts.



- [autohint] Now skips comment lines in fontinfo file.
- [makeotf] Added support for source font files in the 'detype1'
plain text format. Added logic for "Language" keyword in fontinfo
file; if present, will attempt to set the CID font makeotf option
-"cs" to set he Mac script value.
- [compareFamily] Added check in Family Test 10 that font really is
monospaced or not when either the FontDict isFixedPitch value or the
Panose value says that it is monospaced.
- [spot] Fixed bug that kept 'palt'/'vpal' features from being
applied when proofing kerning.



- [makeotf] When building OpenType/TTF files, changed logic to copy
the OS/2 table usWinAscent/Descent values over the head table
yMax/yMin values, if different. This was because:

- both pairs are supposed to represent the real font bounding box
top and bottom,and should be equal;
- the TTF fonts we use as sources for makeotf are built by FontLab;
- FontLab defines the font bounding box for TrueType fonts by using
off-curve points as well as on-curve points. If a path does not have
on-curve points at the top and bottom extremes, the font bounding
box will end up too large. The OS/2 table usWinAscent/Descent
values, however, are set by makeotf using the converted T1 paths,
and are more accurate. Note that I do not try to fix the head table
xMin and xMax. These are much less important, as the head table yMin
and yMax values are used for line layout by many apps on the Mac,
and I know of no application for the xMin and yMin values.

- [makeotf] Changed default Unicode H CMAP file for Adobe-Japan1 CID
fonts to use the UniJIS2004-UTF32-H file.
- Added the CID font vertical layout files used with KozMinPr6N and
KozGoPr6N: AJ16-J16.VertLayout.KozGo and AJ16-J16.VertLayout.KozMin.
- Updated several Unicode CMAP files, used only with CID fonts.
- Added new Perl script,, used in building CID fonts.
This replaces the three scripts,,
and, which have been removed from the AFDKO.



- [makeotf] Discovered that when building TTF fonts, the GDEF table
was not being copied to the final TTF font file. Fixed.



- [autohint] Added new feature to support sets of glyphs with
different baselines. You can now specify several different sets of
global alignment zones and stem widths, and apply them to particular
sets of glyphs within a font when hinting. See option '-hfd' for
- [autohint] Allow AC to handle fonts with no BlueValues, aka
alignment zones.
- [autohint] Respect BlueFuzz value in font.
- [autohint] Fixed the options to suppress hint substitution and to
allow changes.
- [autohint] When hinting a font with no alignment zones or invalid
alignment zones (and with the '-nb' option), set the arbitrary
alignment zone outside the FontBBox, rather than the em-square.
- [checkOutlines] Fixed bug where the arms of an X would be falsely
identified as coincident paths, when they are formed by only two
paths with identical bounding boxes.
- [checkOutlines] Fixed bug where very thin elements would get
identified as a tiny sub path, and get deleted.
- [checkOutlines] Fixed bug in determining path orientation. Logic
was just following the on-path points, and could get confused by
narrow concave inner paths, like parentheses with an inner contour
following the outer contour, as in the Cheltenham Std HandTooled
- [checkOutlines] Fixed bugs in determining path orientation.
Previous logic did not handle multiple inner paths, or multiple
contained outer paths. Logic was also dependent on correctly sorting
paths by max Y of path bounding box. Replaced approximations with
real bezier math to determine path bounding box accurately.
- [checkOutlines] Changed test for suspiciously large bounding box
for an outline. Previous test checked for glyph bounding box outside
of fixed limits that were based on a 1000 em square. The new test
looks only for paths that are entirely outside a rectangle based on
the font's em square, and only reports them: it does not ever
delete them. Added new option '-b' to set the size of the design
square used for the test.
- [checkOutlines] Fixed bug where it would leave a temp file on disk
when processing a Type 1 font.
- [checkOutlines] Removed test for coincident control points. This
has not been an issue for decades. It is frequently found in fonts
because designers may choose to not use one of the two control
points on a curve. The unused control point then has the same
coordinates as its nearest end-point, and would to cause
checkOutlines to complain.
- [compareFamily] Single Test 6. Report error if there is a patent
number in the copyright. Adobe discovered that a company can be sued
if it ships any product with an expired patent number.
- [compareFamily] Single Test 22 (check RSB and LSB of ligature vs.
the left and right ligature components) did not parse contextual
ligature substitution rules correctly. Now fixed.
- [compareFamily] Family Test 18. Survive OTF fonts with no blue
- [compareFamily] Family Test 2 (Check that the Compatible Family
group has same nameIDs in all languages): Added the WPF nameIDs 21
and 22 to the exception list, which may not exist in all faces of a
- [fontsetplot] Fixed so it works with CID fonts. Also fixed so that
widow line control works right. Added new low level option for
controlling point size of group header.
- [fontsetplot] Fixed syntax of assert statements. Produced error
messages on first use of the \*plot commands.
- [kernCheck] Fix so that it survives fonts with contextual kerning.
It does not, however, process the kern pairs in contextual kerning.
- [makeotf] Fixed bug in mark to ligature. You can now use an
`<anchor NULL>` element without having to follow it by a dummy mark
class reference.
- [makeotf] Fixed bug which limited source CID fonts to a maximum of
254 FDArray elements, rather than the limit of 255 FDArray elements
that is imposed by the CFF spec.
- [makeotf] Fixed bugs in automatic GDEF generation. When now GDEF
is defined, all conflicting class assignments in the GlyphClass are
filtered out. If a glyph is assigned to a make class, that
assignment overrides any other class assignment. Otherwise, the
first assignment encountered will override a later assignment. For
example, since the BASE class is assigned first, assignment to the
BASE class will override later assignments to LIGATURE or COMPONENT
- [makeotf] Fix bug in validating GDEF mark attachment rules. This
now validates the rules, rather than random memory. Had now effect
on the output font, but did sometimes produce spurious error
- [makeotf] Fix crashing bug when trying to report that a glyph
being added to a mark class is already in the mark class.
- [makeotf] If the OS/2 code page bit 29 (Macintosh encoding) is
set, then also set bit 0 (Latin (1252). Under Windows XP and Windows
7, if only the Mac bit is set, then the font is treated as having no
encoding, and you cannot apply the font to even basic Latin text.
- [makeotf] By default, set Windows name ID 4 (Full Name) same as
Mac nameID 4, instead of setting it to the PostScript name. This is
in order to match the current definition of the name ID 4 in the
latest OpenType spec. A new option to makeotf ('-useOldNameID4'),
and a new key in the fontinfo file ("UseOldNameID4"), will cause
makeotf to still write the PS name to Windows name ID 4.
- [makeotf] Add support for WPF names, name ID 21 and 22.
- [makeotf] Fixed attachment order of marks to bug in generating
Mark to Ligature (GPOS lookup type 4). The component glyphs could be
- [makeotf] Fixed bug in auto-generating GDEF table when Mark to
Mark (GPOS lookup Type 4) feature statements are used. The target
mark glyphs were registered as both GDEF GlyphClass Base and Mark
glyphs, and the former took precedence. makeotfexe now emits a
warning when a glyph gets assigned to more than one class when
auto-generating a GDEF table GlyphClass, and glyphs named in mark to
mark lookups are assigned only to the Mark GDEF glyph class.
- [makeotf] Fixed bugs in generating TTF fonts from TTF input. It
now merges data from the head and hhea tables, and does a better job
of dealing with the 'post' table. The previous logic made
incorrect glyph names when the glyphs with names from the Mac Std
Encoding were not all contiguous and at the start of the font.
- [makeotf] Added new option '-cn' for non-CID source fonts, to
allow reading multiple global font alignment zones and stem widths
from the fontinfo file, and using this to build a CID-keyed CFF
table with an identity CMAP. This is experimental only; such fonts
may not work in many apps.
- [makeotf] Fixed bug where the coverage table for an element in the
match string for a chaining contextual statement could have
duplicate glyphs. This happens when a glyph is specified more than
once in the class definition for the element. The result is that the
format 2 coverage table has successive ranges that overlap: the end
of one range is the same glyph ID as the start of the next range;
harmless, but triggers complaints in font validators.
- [makeotf] Updated to latest Adobe CMAP files for ideographic
fonts. Changed name of CMAP directories in the AFDKO, and logic for
finding the files.
- [makeotf] When providing a GDEF feature file definition, class
assignments now may be empty:

table GDEF {
GlyphClassDef ,,,;

is a valid statement. You just need to provide all three commas and
the final colon to define the four classes. The following statement
builds a GDEF GlyphClass with an empty Components class.

table GDEF {
GlyphClassDef [B], [L], [M], ;

- [makeotf] The glyph alias file now defines order in which glyphs
are added to the end of the target font, as well as defining the
subset and renaming.
- [makeotf] The `-cid <cidfontinfo>` option for converting a
font to CID can now be used without a glyph alias file, if the
source font glyphs have names in the form "cidXXXX", as is output
when mergeFonts is used to convert from CID to name-keyed. If the
`-cid <cidfontinfo>` option is used, and there is no glyph alias
file, then any glyphs in the font without a name in the form
"cidXXXX" will be ignored.
- [spot] Added error message for duplicate glyph IDs in coverage
tables with format 2, a problem caused by a bug in makeotf with some
Adobe fonts that use chaining contextual substitution. Note: error
message is written only if level 7 GSUB/GPOS dump is requested.
- [spot] Minor formatting changes to the GSUB/GPOS level 7 dump, to
make it easier to edit this into a real feature file.
- [spot] When writing out feature file syntax for GPOS 'ignore
pos' rules, the rule name is now written as 'ignore pos', not
just 'ignore'.
- [spot] Can now output glyph names up to 128 chars (Note: these are
not legal PostScript glyph names, and should be encountered only in
development fonts.)
- [spot] Has new option '-ngid' which suppresses output of the
trailing glyph ID `<gid>` for TTF fonts.
- [spot] No longer dumps the DefaultLangSys entry when there is
- [spot] Changed dump logic for contextual and chain contextual
lookups so that spot will not dump the lookups referenced by the
substitution or position rules in the contextual lookups. The
previous logic led to some lookups getting dumped many times, and
also to infinite loops in cases where a contextual lookup referenced
other contextual lookups.
- [spot] Added support for Apple kern subtable format 3. Fixed old
bug causing crash when dumping font with Apple kern table from
Windows OS.
- [spot] Fixed error when dumping Apple kern table subtable format
0, when kern table is at end of font file.
- [spot] Fixed crashing bug seen in DejaVuSansMono.TTF: spot did not
expect an anchor offset to be zero in a Base Array base Record.
- [spot] Removed comma from lookupflag dump, to match feature file
- [spot] Added logic to support name table format 1, but it probably
does not work, since I have been unable to find a font to test with
this format.
- [spot] Fixed spelling error for "Canadian" in OS/2 code page
- [spot] Changed dump of cmap subtable 14: hex values are
uppercased, and base+UVS values are written in the order [base,
- [stemHist] Always set the alignment zones outside the font BBox,
so as to avoid having the source font alignment zones affect
collection of stem widths.
- [stemHist] Fix bug where the glyph names reported in the stem and
alignment reports were off by 1 GID if the list of glyphs included
the '.notdef' glyph.
- [tx] Added support for option '-n' to remove hints for writing
Type 1 and CFF output fonts.
- [tx] Added new option "+b" to the cff output mode, to force
glyph order in the output font to be the same as in the input font.
- [tx] Fixed bug in flattening 'seac' operator. If the glyph
components were not in the first 256 glyphs, then the wrong glyph
would be selected.
- [tx] Added new library to read in svg fonts as a source. tx can
now read all the SVG formats that it can write. Handles only the
path operators: M, m, L, L, C, c, Z, z, and the font and glyph
attributes: 'font-family', 'unicode', 'horiz-adv-x',
'glyph-name', 'missing-glyph'.
- [tx] Fixed bug in converting TTF to OpenType/CFF. It flipped the
sign of the ItalicAngle in the 'post' table, which in turn flipped
the sign of the OS/2 table fields ySubscriptXOffset and
ySuperscriptXOffset. This bug showed up in TTF fonts built by
makeotf, as makeotf uses 'tx' to build a temporary Type 1 font
from the source TTF.
- [tx] Fixed bug where '-usefd' option was not respected, when
converting from CID to name-keyed fonts.
- Updated the internal Python interpreter to version 2.7.
- Updated Adobe Cmaps/Adobe-Japan1 files:

- Adobe-Japan1\_sequences.txt
- UniJIS-UTF32-H
- UniJIS2004-UTF32-H
- UniJISX0213-UTF32-H
- UniJISX02132004-UTF32-H

- Added several scripts related to CID font production:




- [charplot] This was non-functional since build 21898. Now fixed.
- [checkOutlines] Changed so that the test for nearly vertical or
horizontal lines is invoked only if the user specifies the options
'-i' or '-4', instead of always. It turns out that this test,
when fixed automatically, causes more problems than it cures in CJK
- [compareFamily] Changed so that the default is to check stem
widths and positions for bogus hints. Used 'tx' rather than Python
code for parsing charstring in order to speed up hint check.
- [compareFamily] Updated script tags and language tags according to
OpenType specification version 1.6.
- [documentation] In feature file syntax reference, fixed some
errors and bumped the document version to 1.10.
- [documentation] Fixed typo in example in section 4.d: lookFlag
values are separated by spaces, not commas.
- [documentation] Fixed typo in example in section 8.c on stylistic
names: quotes around name string need to be matching double quotes.
Reported by Karsten Luecke.
- [documentation] Changed agfln.txt copyright notice to BSD license.
- [makeInstances] Fixed bug where a space character in any of the
path arguments caused it to fail.
- [makeInstances] Fixed bug that can make the FontBBox come out
wrong when using ExtraGlyphs.
- [makeInstances] Fixed rounding bug that could (rarely) cause
makeInstances to think that a composite glyph is being scaled (which
is not supported by this script) when it is not.
- [makeotf] Fixed bug in generating TTF fonts from TTF input.
Previous version simply did not work.
- [spot] Added support for "Small" fonts, an Adobe internal
Postscript variant used for CJK fonts.
- [spot] Added support for large kern tables, such as in the Vista
font Cambria, where the size of the kern subtable exceeds the value
that can be held in the subtable "length" field. In this case, the
"length" filed must be ignored.
- [spot] Fixed proof option to show GPOS records in GID order by
default, and in lookup order only with the '-f' option. It had
always been proofing the GPOS rules in lookup order since 2003.
- [spot] Fixed double memory deallocation when dumping TTC files;
this could cause a crash.
- [spot] When decompiling GSUB table to feature file format (-t
GSUB=7) and reporting skipped lookups identify lookups which are
referenced by a chaining contextual rule.
- [sfntedit] Changed final "done" message to be sent to stdout
instead of stderr. Reported by Adam Twardoch.
- [stemHist] Fixed typo in help text, reported by Lee Digidea:
'-all' option was not working.
- [tx] Added new option '-std' to force StdEncoding in output CFF



- [autohint/checkOutlines] Fixed rare case when an _rrcurveto_ is
preceded by such a long list of _rlineto_ that the stack limit is
- [autohint/checkOutlines] Fixed to restore font.pfa output file to
StandardEncoding Encoding vector. Since requirements of CFF
StandardEncoding differs from Type 1 StandardEncoding, a
StandardEncodingEncoding vector in a Type 1 font was sometimes
getting converted to a custom Encoding vector when being
round-tripped through the CFF format which autohint does internally.
- [checkOutlines] Fixed random crash on Windows due to buffer
- [checkOutlines] Changed default logging mode to not report glyph
names when there is no error report for the glyph.
- [CompareFamily] Added "ring" to the list of accent names used to
find (accented glyph, base glyph) pairs for Single Face Test 23.
Reported by David Agg.
- Renamed showfont to fontplot2 to avoid conflict with the Mac OSX
showfont tool.
- Fixed problem with showing vertical origin and advance: was not
using VORG and vmtx table correctly.
- [FontLab scripts] Added logic to Instance Generator to support
eliminating "working" glyphs from instances, to substitute
alternate glyph designs for specific instances, and to update more
Font Dict fields in the instance fonts. Added help.
- Added command line equivalent, "makeInstances' which does the same
thing, but which uses the IS tool for making the snapshot. See the
'IS' entry.
- [IS] Added new tool for "intelligent scaling". This uses the
hinting in an MM font to keep glyph paths aligned when snapshotting
from MM fonts. The improvement is most visible in glyphs with
several elements that need to maintain alignment, such as percent
and perthousand. It is also useful for the same reason when scaling
fonts from a large em-square size to a smaller size. To be
effective, the source MM font must be hinted and must have global
alignment zones defined. The new font must be re-hinted. For
instances from MM fonts especially, it is a good idea to redo the
alignment zones, as the blending of the MM base designs usually does
not produce the best alignment zones or stem widths for the instance
fonts. makeInstances and "Instance Generator" scripts allow you to
preserve these modifications when redoing the MM instance snapshot.
- [makeotf] Fixed generation of version 1.2 GDEF table to match the
final OpenType spec version 1.6. This version is generated only when
the new lookup flag 'UseMarkFilteringSet" is used.
- [makeotf] Fixed generation of names for stylistic alternates
features. There was a bug such that in some circumstances, the
feature table entry for the stylistic alternate feature would point
to the wrong lookup table.
- [makeotf] Fixed generation of the reverse substitution lookup
type. This was unintentionally disabled just before the previous
- [makeotf] Fixed bugs in memory management of glyph objects. If the
font built, it was correct, but this bug could cause the font to
fail to build.
- [spot] Fixed to dump GDEF table version 1.2 according to the final
OpenType spec version 1.6.
- [spot] Fixed feature-format dump of the lookupflags
MarkAttachmentType and UseMarkFilteringSet to give a class name as
an argument, rather than a class index.
- [spot] Extended the GDEF table dump to provide a more readable
- [spot] Added dump formats for htmx and vtmx to show the advance
and side bearing metrics for all glyphs.



- [AGLFN] (Adobe Glyph List for New Fonts) Created new version 1.7.
- [AGLFN] Reverted to the AGLFN v1.4 name and Unicode assignments
for Delta, Omega, and mu. The v1.6 versions were better from a
designer's point of view, but we cannot use name-to-Unicode value
mappings that conflict with the historic usage in the Adobe Glyph
List 2.0. See
- [AGLFN] Dropped all the 'afii' names from the list: 'uni'
names are actually more descriptive, and map to the right Unicode
values under Mac OSX.
- [AGLFN] Dropped all the 'commaccent' names from the list:
'uni' names map to the right Unicode values under Mac OSX before
- [autohint] Converted script to call a command-line program
rather than a Python extension module, same way makeotf works, to
avoid continuing Python version problems.
- [autohint] Fixed to actually emit vstem3 and hstem3 hint operators
(counter control hints, which work to keep the space between three
stems open and equal, as in an 'm') - this has been broken since
the first AFDKO. It will now also look in the same directory as the
source font for a file named "fontinfo", and will attempt to add
stem3 hints to the glyph which are listed by name in the name list
for the keys "HCounterChars" or "VCounterChars".
- [autohint] Fixed old bug where it would only pay attention to the
bottom four of the top zone specified in the FontDict BlueValues
list. This results in more edge hints in tall glyphs.
- [autohint] Fixed special case when adding flex operator which
could result in an endless loop
- [autohint] Added 'logOnly' option, to allow collecting report
without changing the font.
- [autohint] Added option to specify which glyphs to exclude from
- [autohint] Suppressed generation and use of `<font-name>.plist`
file, unless it is specifically requested.
- [autohint] Fixed bug where an extremely complex glyph would
overflow a buffer of the list of hints.
- [checkOutlines] Improved overlap detection and path orientation:
it will now work with outlines formed by overlapping many stroke
elements, as is sometimes done in developing CJK fonts.
- [checkOutlines] added new test for nearly vertical or horizontal
lines. Fixed bug in this new code, reported by Erik van Blokland.
- [CompareFamily] For the warning that the Full Family name in the
CFF table differs from that in the name table, changed it to a
"Warning" rather than "Error", and explained that there is no
functional consequence.
- [CompareFamily] Removed check that Mac names ID 16 and 17 do not
exist, as makeotf now does make them. See notes in MakeOTF User
Guide about this.
- [CompareFamily] Fixed so it works with TTF fonts again.
- [makeotf] Removed code that added a default Adobe copyright to the
name table if no copyright is specified, and removed code to add a
default trademark.
- [makeotf] Added support for the lookupflag UseMarkFilteringSet.
This is defined in the proposed changes for OpenType spec 1.6, and
is subject to change in definition.
- [makeotf] Dropped restriction that vmtx/VORG/vhea tables will only
be written for CID-keyed fonts. The presence in the feature file of
either a 'vrt2' feature of vmtx table overrides will now cause
these tables to be written for both CID-keyed and name-keyed fonts.
- [makeotf] Added warning when a feature is referenced in the aalt
feature definition, but either does not exist or does not contribute
any rules to the aalt feature. The aalt feature can take only single
and alternate substitution rules.
- [makeotf] Added support for the following lookup types:

- GSUB type 2 Multiple Substitution
- GSUB type 8 Reverse Chaining Single Substitution
- GPOS type 3 Cursive Adjustment
- GPOS type 4 Mark-to-Base Attachment
- GPOS type 5 Mark-to-Ligature Attachment
- GPOS type 6 Mark-to-Mark Attachment

- [makeotf] Added support for explicit definition of the GDEF table,
and automatic creation of the GDEF when any of the lookup flag
settings for ignoring a glyph class is used, or any mark classes are
- [makeotf] Support using TTF fonts as input, to build an
OpenType/TTF font, with the limitation that glyph order and glyph
names cannot be changed. This is rather ugly under the hood, but it
works. The Python script uses the tx tool to convert the
TTF font to CFF data without changing glyph order or names. It then
builds an OpenType/CFF font. It then uses the sfntedit tool to copy
the TTF glyph data to the OpenType font, and to delete the CFF
- [makeotf] Added support for building Unicode Variation Selectors
for CID-keyed fonts, using the new cmap subtable type 14.
- [makeotf] Fixed bug with inheritance of default rules by scripts
and languages in feature file feature definitions. Explicitly
defined languages were only getting default rules defined after the
last script statement, and when a script is named, languages of the
script which are not named got no rules at all.
- [makeotf] Fixed bug where you could not run makeotf when the
current directory is not the same is the source font's home
- [makeotf] Set OS/2.lastChar field to U+FFFF when using mappings
beyond the BMP.
- [makeotf] Create the Mac platform name table font menu names by
the same rules as used for the Windows menu names. Add new keywords
to the FontMenuNameDB file syntax. If you use the old keywords, you
get the old format; if you use the new syntax, you get nameIDs 1, 2
and 16 and 17 just like for the Windows platform.
- [makeotf] Fixed bug in name table font menu names: if you entered
a non-English Preferred name ("f=") and not a compatible family
name ("c="), you would end up with a nameID 16 but no nameID 17.
- [makeotf] Fixed bogus 'deprecated "except" syntax' message
under Windows.
- [makeotf] Fixed bug where contextual pos statements without
backtrack or lookahead context were writing as a non-contextual
rule. Reported by Karsten Luecke.
- [makeotf] Added new option to make stub GSUB table when no GSUB
rules are present.
- [makeotf] Added warning if the aalt feature definition references
any feature tags that either do not exist in the font, or do not
contribute any rules that the aalt feature can use.
- [sfntdiff] Fixed so that only error messages are written to
stderr; all others now written to stdout.
- [sfntdiff] Fixed bug in dump of 'name' table: when processing
directories rather than individual files, the name table text was
never updated after the first file for the second directory.
- [spot] Fixed option '-F' to show the contextual rule sub-lookup
indices, and to flag those which have already been used by another
- [spot] If a left side class 0 is empty, do not report it.
- [spot] For GSUB/GPOS=7 FEA dump, give each class a unique name in
the entire font by appending the lookup ID to the class names. It
was just `[LEFTCLASS]()<class index>_<subtable index>`, but
these names are repeated in every lookup. It is now
`LEFTCLASS_c<class index>_s<subtable index>_l<lookup
- [spot] When a positioning value record has more than one value,
print the full 4 item value record. Previously, it would just print
non-zero values. This was confusing when dumping Adobe Arabic, as
you would see two identical values at the end of some pos rules. In
fact, each of these pos rule does have two adjustment values, one
for x and one for y advance adjustment, that happen to be the same
numeric value.
- [spot] Fixed to write backtrack context glyphs in the right order.
- [tx] Added option to NOT clamp design coordinates to within the
design space when snapshotting MM fonts.
- [tx] Added option to subroutinize the font when writing to CFF.
This option is derived from the same code used by makeotfexe, but
takes only about 10% the memory and runs much faster. This should
allow subroutinizing large CJK fonts that makeotfexe could not
handle. This is new code, so please test results carefully, i.e. if
you use it, always check that the flattened glyphs outlines from the
output font are identical to the flattened glyph outlines from the
input font.
- [ttxn] Added options to suppress hinting in the font program, and
version and build numbers.



- [compareFamily] Fixed Single Test 3 (reported by Mark Simonson and
others); the test should compare the Mac platform name ID 4 (name ID
1 + space + name ID 2) with the target value, but was instead using
the value of the name ID 18 (Compatible Full Name).
- [compareFamily] Fixed Family Test 2 to print a report that helps
determine which {platform, script, language, name ID} is present in
some fonts but not others.
- [IS] Fixed a bug where applying hint-based scaling can cause an
off-by-1 error when the the _closepath_ position is supposed to
coincide with the original _moveto_, leading to an effective final
1-unit _lineto_, that may overlap the initial path. In the old MM
design world, we worked around this issue by designing the MMs so
that there was always a one unit difference between a final _curveto_
point and the original _moveto_. FontLab doesn't support doing that
automatically, so when making an instance, **IS** will instead simply
look for cases where the _moveto_ and _closepath_ positions differ by
one unit, and move the _moveto_ position to coincide with the
_closepath_ position.
- [makeotf] Fixed bug where specifying thousands of singleton kern
pairs could silently overflow offsets, and makeotf would build a bad
font without any warning. (reported by Adam Twardoch)
- [makeotf] Relative file paths can now be used even if the current
directory is not the source font directory. Project files can now be
saved to directories other than the source font directory. Note that
paths stored in project file are relative to the project file's
directory. (reported by Andreas Seidel)
- [makeotf/spot] Added support for Unicode Variation Sequences (UVSes).
See MakeOTF User's Guide and
[Unicode Technical Standard 37](
- [spot] Fixed bug where contents of 'size' GPOS feature would be
printed for all dump levels.
- [spot] Fixed failure to process 'post' table format 4.0. which
occurs in some Apple TT fonts, such as Osaka.dfont
- Updated Adobe-Japan-1 CMAP files for building CID fonts.



- Added `featurefile.plist` for BBedit. Install this in the location
shown at the top of the file; it enables code coloring for FEA syntax.
The file is in FDK/Tools/SharedData
- Added `MSFontValidatorIssues.html` to FDK/Technical Documentation. It
lists the error messages from the MS FontValidator tool that can be
ignored for OpenType/CFF fonts.
- [FontLab macros] Added InstanceGenerator. Another script for making
instances from an MM VFB font. It's simpler than MakeInstances macro.
- [FontLab macros] Removed debug statement in Set Start Points which
blocked processing more than 50 glyphs. (reported by George Ryan)
- [FontLab macros] Added explanation of CheckOutlines errors to help
- [checkOutlines] Added option '-he' to print explanation of error
- [compareFamily] Added error if the font's CFF table contains a
Type 2 `seac` operator. The CFF spec does not support this operator.
Some very old tools allow this to happen.
- [makeotf] Fixed a bug in decomposing glyphs that are defined as
composite glyphs in a Type 1 source font. This bug caused the base
component to be shifted when then left side bearing of the composite
glyph differs from that of the base glyph. This could be consequential,
as FontLab has an option to not decompose composite glyphs when
generating a Type 1 font.
- [makeotf] Fixed a bug in recognizing the "Korea1" order when trying
to pick a default Mac cmap script ID from a CID-keyed font's ROS
(Registry-Order-Supplement) field.
- [tx] Fixed a bug in decomposing pretty much all composite glyphs
from Type 1 and CFF source fonts. It happened only when a Type 1 or
CFF font was being subset, i.e. converted into a font with fewer
glyphs. tx now has the option '+Z' to force this to occur.



- [autohint] Added a new option to allow extending the list of glyph
names for which autohint will try to make counter hints.
- [autohint] Fixed bug where Type 2 operator stack limit could be
exceeded when optimizing Type 2 charstrings during conversion from
bez format.
- [autohint] Fixed bug in setting OtherBlues alignment zone values.
- [FontLab macros] The Autohint macro behaves quite differently when
adding 'flex' hints is turned off; it makes more hint substitutions,
since these are not allowed within the segment of the outline that
contributes the 'flex' stem. Turned it on, so that hint results will
be the same as the command-line tool. This does not affect the outline
- [checkOutlines] Fixed bug that prevented the reporting of two
successive points with the same coordinates. The code to convert from
the source outline data to bez format was suppressing zero-length line
segments, so the checkOutlines module never experienced the problem.
- [compareFamily] Added new options '-st n1,n2..' and '-ft n1,n2..' to
allow executing only specific tests.
- [compareFamily] Fixed test "Warn if a style-linked family group does
not have FamilyBlues". When reporting the error that FamilyBlues differ
in a style-linked family group (where at least one font does have real
FamilyBlues), use BlueValues as implied FamilyBlues when the latter
attribute is missing from a font. Same for FamilyOtherBlues.
- [compareFamily] Warn about zones outside of font's BBox only if the
entire zone is outside of the BBox, not just one edge, and warn only
for BlueValue zones, not FamilyBlueValue zones.
- [compareFamily] Fixed fsType check. Complain if fsType is not 8 only
for Adobe fonts, determined by checking if the name table trademark
string is empty or contains "Adobe".
- [compareFamily] Fixed Single Face Test 3 to compare the CFF Full Name
with the name table Preferred Full Name (ID 18) rather than the Full
Name (ID 4).
- [compareFamily] Fixed bug where it failed with CID fonts, because it
referenced the "Private" dict attribute of the font's topDict, which
does not exist in CID fonts.
- [compareFamily] Fixed 'size' test to support the format that indicates
only intended design size, where no range is supplied.
- [compareFamily] Fixed ligature width check to also check that left
and right side bearings match those of the left and right components,
and to use the 'liga' feature to identify ligatures and their components,
instead of heuristics based on glyph names.
- [makeotf] Disallowed negative values in the feature file for the OS/2
table winAscent and winDescent fields.
- [makeotf] Fixed a bug where a lookup excluded with the `exclude_dflt`
keyword was nevertheless included if the script/language was specified
with a languagesystem statement.
- [makeotf] Fixed issue on Windows where a user would see a debug
assert dialog when the OS/2 vendorID was not specified in the feature
file, and the Copyright string contained an 8-bit ASCII character, like
the 'copyright' character.
- [makeotf] Fixed issue on Windows where name ID 17 would be garbage if
no FontMenuNameDB was supplied, and the PostScript name did not contain
a hyphen.
- [makeotf] Added warning for Mac OSX pre 10.5 compatibility: total size
of glyphs names plus 2 bytes padding per glyph must be less than 32K, or
OSX will crash.
- [makeotf] Fixed crash that occurred if the feature file did not have
a languagesystem statement.
- [makeotf] Fixed bug in subroutinizer which allowed a subroutine stack
depth of up to 10, but the Type 1 and Type 2 specs allow only 9. This
caused most rasterizers to declare the font invalid.
- [makeotf] Removed '-cv' option; CJK vertical CMaps have not been
supported since FDK 1.6.
- [spot] Added support for low-level and feature file style
text dumps of GPOS Attachment formats 3, 4, 5 and 6.
- [spot] Added dump of lookup flag value to the feature-file style

contextual substitutions.
- [spot] Fixed bug in GSUB lookup 5, causing crash in dumping trado.ttf.
- [spot] Fixed bug in level 7 (feature-file syntax) dump of GPOS table;
was omitting the value record for extension lookup types.
- [spot] Fixed crash on Windows when proofing contextual substitution
- [spot] Made Windows version behave like Mac when proofing: PostScript
file data is always sent to standard output, and must be re-directed to
a file.
- [spot] Improved documentation of proofing output and '-P' option.
- [spot] Fixed DSIG table reporting of TTC fonts with the version 2 TTC
header, even if the header reports it is version 1, like meiryo.ttc.
- [spot] Enabled proofing TTC fonts that don't have glyph names in the
post table.
- [spot] Fixed origin offset of bounding box for TTF fonts.
- [spot] Fixed crash in proofing TTF fonts when the last glyph is
non-marking, like trado.ttf in LongHorn.



- [autohint/checkOutlines/ProofPDF] Fixed glyph name handling to avoid
stack dump when glyph is not in font. Added support for CID values that
are not zero-padded to 5 hex digits.
- [autohint] Fixed bug where edge hints would be generated rather than
regular hints across the baseline, when there were fewer than 8 pairs of
- [checkOutlines] Fixed bug where it would not report an overlap if
there were an even number of overlapping contours.
- [compareFamily] Fixed Italic angle Single Test 12 to look at the middle
third of the test glyph stems, rather than the top and bottom of the
glyph bounding box, when guessing the font's italic angle.
- [compareFamily] Fixed Single Test 15 to allow a difference of 1 unit in
the font BBox, to allow for rounding differences.
- [compareFamily] Fixed Single Test 26 to identify uXXXX names as valid
Unicode names; had bug in the regular expression that required 5 digits.
- [compareFamily] Fixed Single Test 22 to treat glyphs in the combining
mark Unicode range u3000-u036F range as accent glyphs; require that they
have the same width as the base glyph.
- [compareFamily] Changed report from Error to Warning for check that
only the first four Panose values are non-zero.
- [compareFamily] Fixed bug that caused a stack dump in Single Test 16
and 22.
- [compareFamily] Added tests for Mac OSX pre 10.4 compatibility: no
charstring is < 32K, total size of glyphs names plus padding is less
than 32K.
- [compareFamily] Added test that known shipping font does not have OS/2
table version 4, and that new fonts do.
- [compareFamily] Fixed Single Test 11: allow BASE offset to differ from
calculated offset by up to 10 design units before it complains.
- [compareFamily/makeotf] Fixed failure when tools path contains a space.
- [kernCheck] New tool; looks for kern GPOS rules that conflict, and also

subtables for kerning rules that mask each other.
- [makeotf] Fixed '-adds' option.
- [makeotf] Added new option '-fi' to specify path to fontinfo file.
- [makeotf] Added new option '-rev' to increment the fontRevision field.
- [makeotf] If the (cid)fontinfo file contains the keyword/value for
FSType, will check that the value is the same as the OS/2 fsType field
in the final OTF font. This has to do with historic Adobe CJK font
development practices.
- [makeotf] Added support for setting some of the Plane 1+ bits in the
OS/2 ulUnicodeRange fields.
- [mergeFonts] Will now apply to the output font the values for the
fields Weight and XUID, from the cidfontinfo file.
- [spot] Added support for showing some of the Plane 1+ bits in the OS/2
ulUnicodeRange fields.
- [stemHist] When requiring that reports not already exist, don't delete
older stem reports when asking for new alignment zone reports, and
- [] New tool to pick standard stem hint values. This Perl
script takes in the report from stemHist, and recommends a set of values
to use for the Type 1 font standard stem arrays. This is not as good as
choosing the most relevant values yourself, but better than not providing
any values.
- In _Overview.html_, added warning about 'languagesystem Dflt dflt' and FDK
1.6 feature files.
- In _MakeOTFUserGuide.pdf_, expanded discussion of fontinfo file, updated
documentation of OS/2 v4 table bits with Adobe's practices for the next
library release.
- In _OT Feature File Syntax.html_, fixed incorrect sign for winAscent
keyword, extended discussion of DFLT script tag and useExtension keyword,
and fixed minor typos.

- [compareFamily] Added test for existence and validation of BASE table
in Single Test 11.
- [compareFamily] Fixed bug where failed when reporting font BBox error.
- [compareFamily] Added test that some specific glyph names were not
changed from previous version of font, in Single Test 26.
- [compareFamily] Added "Single Face Test 27: Check
strikeout/subscript/superscript positions". Checks values against default
calculations based on the em-box size.
- [compareFamily] Added "Single Face Test 28: Check font OS/2 codepages
for a common set of code page bits". Checks OS/2 ulCodePageRange and
ulUnicodeRange blocks against the default makeotf heuristics.
- [compareFamily] Added in Single Test 12 a rough calculation of the
italic angle. Warns if this is more than 3 degrees different than the
post table Italic angle value.

preferred family have the same hhea table underline size and position
- [compareFamily] Added "Family Test 16: Check that for all faces in a
preferred family group, the width of any glyph is not more than 3 times
the width of the same glyph in any other face".
- [compareFamily] Fixed Family Test 3 to be more efficient.
- [makeotf/makeotfexe] Added a new option '-maxs `<integer>`' to limit
the number of subroutines generated by subroutinization. Used only when
building test fonts to explore possible errors in processing the
- [makeotf/makeotfexe] Allow working names to be longer than 31
characters; warn but don't quit, if final names are longer than 31



- [makeotf] Fixed bug where 'size' feature was built incorrectly when it
was the only GPOS feature in the font.
- [spot] Improved error messages for 'size' feature problems.
- [compareFamily] Added dependency on environment variables:
**CF_DEFAULT_URL** should be set to the foundry's URL; it's compared
with name ID 11.
**CF_DEFAULT_FOUNDRY_CODE** should be set to the foundry's 4-letter
vendor code; it's compared with OS/2 table achVendID field.
- [compareFamily] Check that CFF PostScript name is the same as Mac and
Windows name table name ID 6.
- [compareFamily] Check that named IDs 9 and 11 (designer name and
foundry URL) exist.
- [compareFamily] Extended Single Test 4 to verify that version string
is in correct format '(Version|OTF) n.nnn'.
- [compareFamily] Improved Panose test to check that values are not all
0, and that the CFF font dict 'isFixedPitch' field matches the Panose
monospace value.
- [compareFamily] Added check to confirm the presence of Unicode cmap
sub table.
- [compareFamily] Added check to confirm that latn/dflt and DFLT/dflt
script/languages are present, if there are any GPOS or GSUB rules. Also
checks that script and language tags are in registered lists, and that
all faces have the same set of language and script tags, and feature
list under each language and script pair.
- [compareFamily] Added check to confirm that all faces in the family
have the same OS/2 table fsType embedding permission values.
- [compareFamily] Added check to confirm that if font has Bold style
bit, the CFF forceBold flag is on. Also vice-versa, if the font weight
is less than 700.
- [compareFamily] Added check to confirm that the font does not have a
UniqueID or XUID, if it's not CID-keyed.
- [compareFamily] Added glyph name checks: OS/2 default char is .notdef,
and that there are NULL and CR glyphs in TrueType fonts, and that names
conform to the current Adobe Glyph Dictionary. Note that latest practice
is to use 'uni' names for final names for all the 'afii' glyphs.
- [compareFamily] Fixed family BlueValues tests to compare within
compatible family name groups.
- [compareFamily] Changed Family Test 2 to check that all name IDs
except 16, 17, 18, are all present with the same language/script values
within all faces of a preferred family.
- [compareFamily] Changed Single Test 3, which didn't do at all what it
- [FontLab macros] Fixed bug introduced when changing modules shared
with command-line scripts in build 19.



- [ProofPDF] Fixed bug in waterfallplot mode, where Acrobat would
report the output PDF file as being damaged.
- [makeotf] Fixed bug that prevented building CID fonts in release
mode, introduced in build 19.



- [compareFamily] Added Family Test 13 to report error if two fonts in
the same preferred family have the same OS/2 weight, width and Italic
settings, and the OS/2 version is greater than 3. Also reports an error
if the fsSelection field bit 8 "WEIGHT_WIDTH_SLOPE_ONLY" is set
differently across faces of the same preferred family name group.
- [compareFamily] Fixed Family Test 12 to not fail when the font has a
script/language with no DefaultLangSys entry.
- [makeotf] If a font file with the requested output file name already
exists, will delete it before running makeotfexe, so can tell if it
- [makeotf] Will now set the new 'fsSlection' bits if the following
key/value pairs are in the 'fontinfo' file:

PreferOS/2TypoMetrics 1
IsOS/2WidthWeigthSlopeOnly 1

baseline can be set correctly when proofing a font file without a BASE
- [digiplot] Allowed using a CID layout file to supply meta info when
proofing name-keyed fonts.

entries in the font Private font-dictionary.
- [checkOutlines] Fixed writing out the changes when fixing outlines.
- [checkOutlines] Fixed bug that mangled outlines when three alternating
perpendicular lines or vh/hv/vv/hh curveto's followed each other.

screen. Added option to set log file path, and added numeric suffix to
name so as to avoid overwriting existing log files.
- [compareFamily] Fixed issue that happened when looking through the
directory for font files, when encountering a file for which the user
did not have read permission.
- [compareFamily] Added Single Test 24: check that 'size' feature
Design Size is within the design range specified for the font.

- [makeotf] Added new option '-osv `<number>`' to allow setting the OS/2
table version number.
- [makeotf] Added new option '-osbOn `<number>`' to set arbitrary
bitfields in OS/2 table 'fsSelection' to on. May be repeated more than
once to set more than one bit.
- [makeotf] Added new option '-osbOff `<number>`' to set arbitrary
bitfields in OS/2 table 'fsSelection' to off. May be repeated more than
once to unset more than one bit.
- [makeotf] If neither '-b' nor '-i' options are used, check for a file
'fontinfo' in the same directory as the source font file, and set the
style bits if these key/values are found:

IsBoldStyle true
IsItalicStyle true

- [FontLab macros] Built the autohint and checkOutline libraries (PyAC
and focusdll) linked with Python2.3 so they work with FontLab 5.
- [mergeFonts] Added option to copy only font metrics from first source
- [mergeFonts] Allow empty lines and "" comment lines in glyph alias
and in cidfontinfo files.
- [rotateFont] Fixed bug where it did not allow negative numbers.
- [rotateFont] Allow empty lines and "" comment lines in rotation info
- [sfntedit] Fixed so that it will not leave the temp file behind on a
fatal error, nor quit because one already exists.
- [spot] Fixed order of backtrack glyphs in dump of chaining contextual
`sub` and `pos` statements. Now assumes that these are built in the
correct order.
- Added two new tools, **type1** and **detype1**, that compile/decompile
a Type 1 font from/to a plain text representation.



- [compareFamily] Added warning if sum of OS/2 table sTypoLineGap,
sTypoAscender, and sTypoDescender is not equal to the sum of usWinAscent
and usWinDescent.
- [compareFamily] Updated test for allowable weights in style-linked
faces to reflect the current behavior of Windows XP.

(Full Name) is the same as the PostScript name.
- [compareFamily] Added report on sets of features in different
languagesystems, and an error message if they are not the same in all
faces of the font.
- [compareFamily] Fixed incorrect message about real error when menu
names are not correctly built.
- [compareFamily] Fixed test for improbable FontBBOX to use em-square
rather than assume 1000 em.

than the width of the first glyph.
- [compareFamily] Added warning if accented glyphs have a width different
than their base glyph.
- [compareFamily] Added error message if two faces in the same family
have the same OS/2 width and weight class and italic style setting, and
are not optical size variants. Optical size check is crude: the Adobe
standard optical size names (Caption, Capt, Disp, Ds, Subh, Six) are
removed from the PS font names and then compared; if the PS names are
the same, then they are assumed to be optical size variants.
- [compareFamily] Added check that no hint is outside the FontBBox, for
CJK fonts only.
- [spot/otfproof] Added "Korean" to list of tags for OS/2 codepage range.
- [spot/otfproof] Fixed dump of 'size' feature to support correct and old

format 3.
- [spot/otfproof] Added warnings that only low-level dump of other
contextual lookups is supported.
- [makeotf] Program is now a stand-alone C executable.
- [makeotf] Removed option to write contextual positioning rules in the
_old_ incorrect format.
- [makeotf] MakeOTF no longer assigns Unicode Private Use Area values
to glyphs for which it cannot identify. To use PUAs, explicitly assign
them in the GlyphOrderAndAlias file.
- [makeotf] Fixed bug in name table name ID "Version": if version decimal
value is x.000, then the value in the Version name ID string was x.001.
- [makeotf] Fixed bug in handling of DFLT language script: it's now
possible to use this tag.
- [makeotf] Fixed feature file parsing bug where 'dflt' lookups in one
feature were applied to the following feature if the following feature
started with a language statement other than 'dflt'.
- [makeotf] Fixed serious bug where wrong width is calculated for glyphs
where the CFF font Type 2 charstring for the glyph starts with a width
value. This is then followed by the value pairs for the coordinates for
the vertical hint, and then these are followed by a hint mask or control
mask operator. The bug was that when MakeOTF reads in the charstring in
order to derive the hmtx width, it discards the data before the control
mask operator, leading the parser to use the CFF default width for the
- [makeotf] vhea.caretSlopeRise and vhea.caretSlopeRun is now set to 0
and 1 respectively, rather than the opposite.
- [makeotf] The OS/2 table 'fsType' field is now set to the feature file
override. If not supplied, then the value of the environment variable
FDK_FSTYPE. If not set then 4 (Preview & Print embedding).
- [makeotf] Added support for contextual chaining positioning of base
glyphs; mark and anchors not yet supported.
- [makeotf] Fixed bug in 'size' feature: the feature param offset is now
set to the offset from the start of the feature table, not from from the
start of the FeatureList table.
- [makeotf] Allowed 'size' feature point sizes to be specified as
decimal points, as well as in integer decipoints.

- [makeotf] Added hhea overrides for Ascender/Descender/LineGap.
- [makeotf] Set OS/2 Unicode coverage bits only if the font has a
reasonable number of glyphs in the Unicode block; it was setting the
bits if the font had even one glyph in the block.
- [makeotf] The "Macintosh" codepage bit in the OS/2 codePageRange fields
is now set by default.
- [FEA spec] Fixed incorrect range example in section _2.g.ii. Named
glyph classes_
- [FEA spec] Changed rule to allow lookup definitions outside of feature
definitions in FDK 2.0.
- [FEA spec] Fixed incorrect uses of 'DFLT' rather than 'dflt' for a
language tag.



- [OTFProof] Fixed error in dumping GSUB table: GSUB lookup 5,
context lookup assumed that there were both a lookahead and a backtrack
- Updated SING META table tags to latest set.



- [makeotf] Fixed rule in building CJK font. When looking for Adobe
CMap files, will no longer use a hardcoded max supplement value when
building paths to try.



- [compareFamily] Fix stack dump when family has no BlueValues
(reported by House Industries).
- [compareFamily] Fix stack dump when CFF-CID font has glyph with no
`subr` calls.
- [OTFProof] Corrected error in last release, where spaces between
ligature match string names were omitted.
- [FontLab macros] Added scripts for testing if the joins in a
connecting script font design are good.
- [OTFProof] Fixed crash on proofing or dumping feature file syntax for
GSUB lookup 5, context lookup. Also fixed rule-generating logic:
results were previously wrong for proof and for feature-file syntax
formats. Text dump has always been correct.
- [OTFProof] Fixed crash when dumping cmap subtables that reference
virtual GIDs not in the font.
- [OTFProof] Fixed crash on dumping GSUB lookup type 6 chaining context
subtable format 2. This has never worked before.
- [OTFProof] Added demo for SING glyphlet tables, SING and META.
- [FontLab macros] Added scripts for reading and writing an external
composites definition text file.
- [FontLab macros] Added scripts for working with MM fonts.



- [OTFProof] Fixed crash after dumping contents of ttc fonts (bug
introduced in version 6792).
- [OTFProof] Fixed cmap subtable 4 and 2 dumps. Cmap subtable 2 could
show encoding values for single byte codes which were really the
first byte of two byte character codes. In Format 4, idDelta values
were not being added when the glyphindex was derived from the glyph
index array. These show issues show up in some TTF CJKV fonts.



- [OTFProof] Fixed crash when proofing fonts with _many_ glyphs.
- [OTFProof] Restored "skipping lookup because already seen in
script/language/feature" messages to proof file, which was lost in
version 6604.
- [OTFProof] Added ability to proof resource fork sfnt fonts from Mac
OSX command line. It's still necessary to use the SplitForks tool to
make a data-fork only resource file, but spot/otfproof can now navigate
in the resulting AppleDouble formatted resource file.
- [OTFProof] Added support for a text dump of the GDEF table.
- [OTFProof] Changed title in 'size' feature dump from _Common
Characters_ to _name table name ID for common Subfamily name for size
- [AGL] Fixed some minor errors in the Adobe Glyph List For New Fonts.



- [OTFProof] Fixed bug in dumping KERN table from Mac sfnt-wrapped
resource fork Type 1 MM font.
- [OTFProof] Changed the AFM-format dump of kern pairs to list all
kern pairs for each language/script combination in separate blocks, and
to eliminate all class kern pairs that are masked by a singleton kern
pair. The temp buffer file path is now taken from the system C library
function tmpnam(), and is not necessarily in the current directory.



- [OTFProof] Fixed command-line tool to write proof files in same
location as font, and with font-name prefix, when not auto-spooled for
- [OTFProof] Fixed bug in UI version where proofing GSUB features and
then GPOS features would cause the GPOS feature proof files to be empty.
- [makeotf] Fixed heuristics for picking OS/2 weight/width so that a
font name containing _ultracondensed_ would trigger only setting the
width, and not the weight as well.
- Updated Mac OS project files to CodeWarrior 8.



- [OTFProof] When dumping data from TTF fonts, now add `<gid>` to all
glyph names. This is because the rules for deriving names can lead to
two glyphs being given the same name.
- [OTFProof] Fixed bug in proofing GPOS class kern pairs: was generating
bogus kern pairs and duplicate kern pairs when the coverage format was
type 2. Affects proof file only, not AFM or feature-format dump.
- Fixed memory overwrite bug encountered by Goichi and cleaned up various
memory leaks in the process.
- [compareFamily] Added report on whether a face contains known std
charset. Stub implementation - still need list of std charsets.
- [AFM2Feat] Developed tool to convert an AFM file to a file with
kern feature `pos` rules.



- Rebuilt all libraries for v1.6 release 3/10/2003.

converting the Adobe Type Library. Maps all the old glyph names to AGL
compatible names.



- [OTFProof] Fixed crash in handling of VORG with no entries. (Vantive
- [MakeOTF] Updated documentation: added a description of how all three
columns of the _GlyphOrderAndAliasDB_ file are used; added a new section
on the key-value pairs of the font project file; updated the description
of the FontMenuNameDB file entries; added minor clarifications throughout.
- Updated _digital_signature_guide.htm_ to match current Verisign website.
- [Example fonts] Changed the incorrect language keyword TUR to TRK.
- [Example fonts] Removed the many key/value pairs in the fontinfo files
that are not used by MakeOTF.
- [OTFProof/spot] Fixed 3-column handling of GOAADB. (Vantive 569681)



- [MakeOTF] Suppressed the "repeat hint substitution discarded" message
from the source file parsing library. These are so common that they
obscure more useful messages.
- [MakeOTF] Set as default the option to build chaining contextual
substitution rules with the incorrect format used by InDesign 2.0 and
- [MakeOTF] If the option above is set, then MakeOTF will write a name
ID (1,0,0,5 - "Version") which will contain the text string which
triggers special case code in future Adobe apps so that it will process
the chaining contextual substitution rules as they were intended. If
this option is NOT set, the name ID 5 will be written so as to not
trigger this special case code. The special case treats specially any
font where the name table name ID (1,0,0,5) exists and either matches,

"OTF[^;]+;PS[^;]+;Core 1\.0\.[23][0-9].*"

(example: "OTF 1.006;PS 1.004;Core 1.0.35")
or contains,


(example: "Core 1.0.38;makeotf.lib1.5.4898")
or just,


- [MakeOTF] Turn off by default the option to force the .notdef glyph
in the output OTF font be an crossed rectangle with an advance width
of 500.
- [MakeOTF] Added rule to force the OS/2 WeightClass to always be at
least 250. Shows error message if set or calculated WeightClass was less
than this.
- [MakeOTF] Added test that FSType is set the same in the feature file
as in source CID font files.
- [OTFProof] Page layout for CJKV font vertical layout: now writes the
vertical columns right to left.
- [OTFProof] When writing vertical features, now shows the advance width
sign as negative.
- [OTFProof] When making PostScript proof file, now writes DSC tags with
correct header and page info.
- Added _Unicode and Glyph Name_ documentation to the FDK _Technical
Documentation_ directory, to allow access to this info under the FDK



- [MakeOTF/FEA syntax] Added new vmtx table overrides, to allow setting
vertical metrics for pre-rotated proportional glyphs that are
specifically designed and are not simply rotated forms of proportional
- [MakeOTF/FEA syntax] Added new OS/2 overrides to set the Unicode and
Windows codepage range fields: UnicodeRange CodePageRange.
- [MakeOTF/FEA syntax] Updated language keywords to be consistent with
OpenType spec, i.e using `dflt` instead of `DFLT`. Expanded section
explaining use of language and script default keywords. Old keywords
still work, but cause a warning to be emitted.
- [FEA syntax] Expanded explanation of kern class pairs and subtable
- [MakeOTF] Updated the search rules for CID font CMap files to support
Adobe-Japan2-0, and to look first for UTF-32 CMAP files.



- Release to Adobe website Sept 2002.



- [MakeOTF] Changed the name table version string to match OT spec 1.4.
- [CompareFamily] Made it _really_ work with Sept 10th 2002 release of
Just van Rossum's FontTools library.



- [MakeOTF] (hotlib 1.0.35) Fixed the error in processing GSUB
contextual chaining substitution format 3. This was originally done
according to the OpenType spec 1.4, which is in error by the
established implementation of VOLT and Uniscribe. Added option '-fc' to
cause the library to use the incorrect implementation, according to OT
spec v1.4. By default, MakeOTF builds the correct contextual format
per spec v1.5.
- [MakeOTF] (hotlib 1.0.35) Fixed Unicode cmap bug in assigning the OS/2
table field usLastCharIndex. This is supposed to be the highest Unicode
value in the BMP-16 cmap tables. The problem was in the logic by which
alternates of supplemental plane glyph names were being assigned an EUS
code, but not added to the BMP-16 Unicode cmap tables, e.g. u1D269.alt.
When one of these alternates was assigned an EUS value, the
usLastCharIndex was getting bumped even though the glyph was not being
added to the BMP-16 cmap tables. Fixed by not incrementing
usLastCharIndex in this case.
- [MakeOTF] Fixed bug in applying client-supplied Unicode override
values. These were omitted if the glyph names in the font were different
than the final glyph names, as can happen when the client uses the
getFinalGlyphName call back to supply a glyph production name which is
different than the final glyph name.
- [OTFProof] Fixed crash when proofing liga feature in CID font. Also
fixed crash when proofing charstring with only one operand, e.g
- [CompareFamily] Updated to use the latest version of Just van Rossum's
FontTools library, added support for TrueType fonts. Now requires Python
- [CompareFamily] Added family test 11: verify that for base font in
style-linked group, Mac and Windows menu names are the same, and that
for other fonts in the style linked group, the Mac and Windows menu
names  differ.



- External release of FDK 1.5 on Adobe website.



- [CompareFamily] Fixed tabular glyph and isFixedPitch test so that they
are now useful - used to generate far too many false errors.
- [MakeOTF] Fixed bug in setting Panose values from a feature file
override. If any value in the Panose value string is 0, all subsequent
values were also set to 0.
- [MakeOTF] Fixed bug where glyphs that got renamed were not subjected
to the ordering specified by the GlyphOrderAndAliasDB file.
- Added file to integrate all tools into a common UI.
- [OTFCompare] Added use of CFFChecker library for CFF table.

- [CompareFamily] Added family test 10: if any face in family has a real
panose value, report derived panose values as an error.
- [CompareFamily] Fixed bug  in comparing copyright notices in family
test 7: will now really report error only if differs in other than years.
- [CFFChecker] Added support for multiple input files.
- [CFFChecker] Added support for resource fork fonts under MacOS 9.
- Added CFFChecker interface to makeotf.
- [OTFCompare] Added OSX prompt-based support.
- Fix R-O-S mapping for CMAP files.
- Fixed getunicodeCmap() to not hard-wire Adobe-Japan1-3 when processing
J fonts.
- [CFFChecker] MacOS 9 version created.
- Added CFFChecker.

- [OTFProof] Fixed vertical metrics proofing.
- [MakeOTF] Added warning when truncating OS/2 TypoAscender to force its
sum with TypoDescender to be equal to the em-box.
- [MakeOTF] Allow fractional synthetic weight values. These are rounded
to an integer.
- [MakeOTF] Changed XUID adding algorithm to NOT add the revision number
to the XUID array.

GSUB=7 dumps.
- [OTFProof] Added support of TT instructions in compound glyphs.
- [CompareFamily] Fixed incorrect unwrapping T2 charstring subroutines.
All previous reports on whether glyphs were hinted should be doubted.

- [MakeOTF] Added support for "italicangle", "width" and "weight" keywords
in FontMenuNameDB.
- [SCM/makeotf/typecomp] Fixed Euro-adding bug.
- [OTFProof] Removed header note "1000 units/em" from proofs.
- [OTFProof] Added support for cmap version 12.
- [OTFProof] Removed zero padding of CID values from text reports.
- [OTFProof] Reduced number of warnings about missing characters.
- [OTFProof] Removed warning when GPOS and GSUB table may be too big,
as no tools make this error anymore, and it is triggered
inappropriately when font uses the extension lookup.
- [OTFProof] Fixed different spacing problem reported. (Vantive 420313)
- [OTFProof] Fixed so that vertical proofs write from right to left.
- [MakeOTF] Fixed problem with unspecified CMap files.

Blues arrays is not present.
- [OTFProof] Fixed so that glyph names for CID fonts print properly.
- [OTFProof] Fixed problems with compile under SunOS.
- [MakeOTF] Added as an example file to edited, in
order to allow scripting of makeOTF on the Mac (or any other platform).
Minor changes to to fix this.
- [MakeOTF] Added an option to allow removing deprecated Type 1 operands
from output font (e.g. `seac` and `dotsection`).
- [MakeOTF] Added an option to allow adding synthesized glyphs to fonts,
leveraging a built-in sans and serif multiple master substitution font.
The source font must contain a 'zero' and a capital 'O'.
The glyphs that can be synthesized are:




- Began tracking files by Perforce changelist label, from the Perforce
source code management system.
- Updated compilers to Mac/CodeWarrior 6 Pro, Windows Visual C++ 6.0.
- Re-organized build directories to have mac/win/sun4 subdirectories.
- Re-organized shared include files to all be under /Programs/api, with
non-conflicting names.
- [Example fonts] Updated MinionPro-Capt: now has correct frac and size
- [Example fonts] Added KozMinPro to samples.
- [MakeOTF] Fixed bug where fontinfo keyword IsStyleBold was ignored for
CID fonts.
- [MakeOTF] Fixed Mac build project to load debug and release libraries
by different names.
- [MakeOTF] Added feature file support for the "languagesystem" statement.
Note that this entailed removing support for script, language, and named
lookup statements in the size feature, and removing support for script and
language statements in the aalt feature. See feature file spec for details.
- [MakeOTF] More descriptive wording in offset overflow error messages.
Feature file error handling improved: multiple error messages are emitted
before failing if possible, instead of just one; final glyph name as well
as glyph alias (if applicable) reported if not found in font.
- [MakeOTF] Changed the 14 Corporate Use subarea Unicode values for Zapf
Dingbats to the proposed UVs in anticipation of their being incorporated
into the Unicode standard.
- [MakeOTF] Added FontWorks ('FWKS') to vendor ID list.
- [MakeOTF] Increased the maximum number of named lookups allowed to 8192.
- [MakeOTF] Now makes kern and vert features from kern data passed in by
clients and from V CMap (respectively) only when the HOT_CONVERSION bit is
set. (Previously, these features were made from the sources mentioned
above if they weren't already defined in a feature file.)
- [MakeOTF] Fixed an obscure bug in OS/2.ulUnicodeRange computation: if
the largest UV in the font were not in any Unicode range recognized by
hotlib then it was counted as being in the next recognized Unicode range
after the UV. (No known fonts are affected by this.)
- [MakeOTF] Forced the OS/2 codepage range bits for Chinese to either
Simplified or Traditional, based on the Mac cmap script, if it is defined
as either Simplified or Traditional, and will fall back to the heuristics
if the script is undefined. If the mac.script is something other than a
Chinese script, then the OS/2 codepage range bits for Chinese will not
be set.
- [OTFCompare] The Python sys.path variable must now contain the path
to the directory containing the OTFProof library (usually
_FDK/Tools/Programs/otfproof/exe_). This replaces the hardcoded path
reference in the script. On all platforms, this is done
by adding the file "otfproof.pth", containing the path, to the Python
- [OTFCompare] Fixed a bug that was causing tables smaller than 16 bytes
to be reported as different
- [OTFProof] Added new proofing mode to CFF_ to print one glyph per page.
- [OTFProof] Added new proofing option to suppress file-specific header
info to facilitate diff-ing of multiple proofs.
- [OTFProof] Added alphabetical sorting of AFM-style dump.
- [OTFProof] Fixed bug causing GPOS/GSUB features with digits in their
names to not appear in the proofing list.
- [OTFProof] Added support for glyphsize option in CFF_ dumps.
- [OTFProof] Fixed conflicting include file names; must now specify
include paths in project file.
- [OTFProof] Reduced some of the recursion in the subroutinization code
to reduce stack space requirements.
- [OTFProof] Fixed support for included feature files in parent folder
on the Mac.



- [OTFProof] Fixed bug where would report error opening Mac TTF suitcase
font, because data fork was of size 0.
- [OTFProof] Fixed bug where feature tags containing numbers were filtered
out of the feature list for proofing.
- [OTFProof] Fixed bug where baseline was shown incorrectly for CJK fonts
with baselines other than 120.
- [OTFProof] Fixed bug where y-placement changes were not shown correctly
in vertical writing mode proofs.



- [MakeOTF] Fixed problem with heuristics for OS/2 codepage range
settings, for Chinese Simplified vs Traditional.
- [MakeOTF] Added macro to define MakeOTF version number.
- [MakeOTF] updated makeotflib help/usage messages: shown when args are
incorrectly formatted.

- [makeotf] (makeotf/exe/

- added fontinfo list entry for "Language".
- added 'parameter' variable entry for same.
- increased num values to from 34 to 35.

which index matches which fontinfo field.

- [makeotf] (makeotf/exe/

- updated version numbers to 1.3.1.
- added '-cs' and '-cl' options to help.
- added processing of Language field, to set script and language IDs
with '-cs' and '-cl' options.

- [makeotf] (makeotf/source/main.c)

- added macro to define MakeOTF version number, used in help message,
and in client name string for name id 5 "Version".
- added mac_script and mac_language fields to global static 'convert'
- added processing of '-cs' and '-cl' arguments to parse_args().
- added mac_script and mac_language arguments to call to cbconvert().
- updated print_usage to match that of
- updated the ReadFontInfo() to process new Language field.

- [makeotf] (makeotf/source/cb.c)

- moved initialization (as type unknown) of mac.encoding, mac.script
and mac.language from cbconvert to cbnew().
- added setting of mac.script and mac.language to cbconvert(), from
- added mac_script and mac_language arguments to call to cbconvert().

- [makeotf] (source/includes/cb.h)

- added mac_script and mac_language arguments to call to cbconvert().

- [hotconvlib] (coretype/source/map.c)

- changed logic for setting OS/2 codepage range to set code page to
Simplified or Traditional Chinese based on mac.script setting;
fallback on heuristics only if mac.script is not set.
