Font Validator is a tool for testing fonts prior to release. | |
It was initially developed by Microsoft, to ensure that fonts meet Microsoft's | |
high quality standards and perform exceptionally well on Microsoft's | |
platform. | |
In 2015 the source code was published under the MIT license ([see release | |
discussion](http://typedrawers.com/discussion/1222/microsoft-font-validato | |
r-lives)) | |
Most (only?) active development happens at | |
http://github.com/HinTak/Font-Validator . | |
FontVal 2.1.6 , Jun 16 2020 | |
============= | |
- small update on non-NULL FeatureParams. | |
FontVal 2.1.5 , Jun 9 2020 | |
============= | |
- No functionality change in the Freetype backend, other than passsively | |
upgrading to VER-2-10-1-71-g4b08cdf78 based on 2.10.1 . | |
- fixed about a dozen of issues /improvements on OS/2, cmap, head, hmtx, | |
name tables. | |
- Thanks Miguel Sousa for patches, Stevan White for many of the issues | |
with SMP / large font sets, and Georg Seifert and Rich Fitzgerald on | |
Mac OS X related issues. | |
- fixes crashes under non-English (French/Russian/Portugese) locales. | |
- Mac binary now based on patched mono | |
( https://github.com/HinTak/mono-modification/ ) | |
- Built and tested on Raspbian too. | |
- The Mac build tested successfully on darling. | |
FontVal 2.1.4 , Nov 29 2018 | |
============= | |
Mostly for fix to https://github.com/HinTak/Font-Validator/issues/39 | |
Since 2.1.3 enabling building with visual studio, the win32+64 binary is now built with visual studio, instead of mono. | |
Apologies the windows build still shows version at 2.1.2: I forgot to bump the version shown up before tagging. This was noticed while I tested the Linux binaries, so the Linux/OSX binaries had the problem corrected. | |
FontVal 2.1.3 , Nov 18 2018 | |
============= | |
*** Re-implementing Visual Studio buildability | |
This is mostly a source-only release to signify that FontVal is now buildable with Visual Studio (Express) 2008+ again, after it was broken just before leaving Microsoft 3 years ago. | |
FontVal 2.1.2 , Sep 6 2018 | |
============= | |
Mostly for mono 5.14-based binary rebuild to fix the $PATH bug ( https://github.com/mono/mono/pull/6147 ) | |
Problems related to building and running FontVal with mono 5 is tracked in https://github.com/Microsoft/Font-Validator/issues/53 . | |
Most windows users should get the win32+64 build, which caters for both 32-bit and 64-bit windows. | |
However, if strange crashes on 64-bit windows happen ( possibly related to harfbuzz - see https://github.com/HinTak/Font-Validator/issues/27 ), the win32 build works around such issue by forcing 32-bit mode even on 64-bit windows. I would appreciate people letting me know and also send the font file, if such a crash happens and the usage of the win32 build becomes necessary. | |
FontVal 2.1.1 , Sep 1 2017 | |
============= | |
- This is an update from FontVal 2.1 on the FreeType backend only, | |
to VER-2-8-100-g587264cfd . | |
We now also offer all-in-one command-line binaries for Ubuntu Linux x86_64 | |
14.04 and 16.04, in addition to Mac OS X. ( Thanks to new functionality | |
in mono introduced in 4.6.0 and matured in 4.8.0 in the last 12 months. ) | |
The Ubuntu 16.04 binary is preferred, as the 14.04 binary is limited | |
by older compiler as mentioned in FontVal 2.1. | |
- as rasterization tests now work on all major platforms, "+raster-tests" | |
will become the default in FontVal 2.2 . | |
- The windows-only "accept non-ascii font names" fix proved to be troublesome | |
and is reverted. Other platforms are not affected and continue to accept | |
non-ascii font file names. | |
Special thanks to Christian Demmer for multiple rounds of patient testing | |
of the Mac OS X binaries! | |
FontVal 2.1 , Jul 20 2017 | |
=========== | |
- Backend b70+10.5, based on FreeType 2.8+ (VER-2-8-73-g38bdf22bf) | |
- 16 Errors/Warnings in 1.0 which has no FreeType equivalent | |
are implemented. This includes incomplete conditionals (e.g. | |
IF without THEN) and maths overflows, etc. | |
- 15 FreeType-specific additions are added. This includes endless loops | |
and backward jumps, etc. | |
- C Python wrapper available ( https://github.com/HinTak/freetype-py | |
fontval-diag branch ). Perl wrapper in dev. | |
- Robustness: still produce a report for some seriously buggy fonts | |
- Speed/Resources improvements: | |
- avoid unnecessary repeated processing of identical EBDT/glyf tables | |
and rasterization for TTCs | |
(down from half-days to an hour or two in some cases) | |
- much smaller memory foot-prints for EBDT check | |
(down from 15 to 20+ GB RAM to 1 or 2 GB in some extreme cases) | |
- Windows-only problem fixed: can now accept non-ascii font names | |
(2.0 did not, 1.0 did). | |
- New opentype tables supported: meta (partial) | |
- glyf table: cope with broken contours with hair pins, and extremely | |
tight loops etc and correctly warn those. | |
- DSIG table: supports stronger cryptographic digest algorithms (Apparently | |
Adobe started signing with those). correct previous mis-diagnosis of very | |
old TTCs' signature. | |
- A lot of misc documentation updates. | |
- Known Caveats: | |
- E6053 (Value exceeds capacity of 2 byte number) also warns on | |
values exceeding Fixed 2.14 (FontVal 1.0 did not). | |
- W6028 (number of twilight points unreasonably large) too frequent/noisy. | |
- W6029 (Setting the loop variable to zero is an error) may be withdrawn | |
later as ttfauthint does it and there is no known problem, despite | |
some apple and macrosoft docs saying so. | |
- The check for maths overflows in hinting instructions requires gcc 5+ to | |
build, so it is not offered on the Mac OS X backend for the time being. | |
FontVal 2.0 , Jul 17 2016 | |
=========== | |
- backend b54, based on FreeType 2.6.4 | |
FontVal 1.1 , Apr 07 2009 | |
=========== | |
- Microsoft released to Github on Nov 11 2015; incomplete | |
FontVal 1.0 , Jul 10 2003 | |
=========== | |
- last known Microsoft's proprietary binary |
