ttfautohint 1.7 has been released.

The source tarball, statically-linked binaries for Win32 (TTY and GUI) and
OS X (TTY only) are available from


Instructions to build the GUI version on OS X can be found at

This project provides a library which takes a TrueType font as the input,
remove its bytecode instructions (if any), and return a new font where all
glyphs are bytecode hinted using the information given by FreeType's
autohinting module.  The idea is to provide the excellent quality of the
autohinter on platforms which don't use FreeType.

The library has a single API function, `TTF_autohint'; see
`lib/ttfautohint.h' for a detailed description.  Note that the library
itself won't get installed currently.

A command-line interface to the library is the `ttfautohint' program; after
compilation and installation, say

  ttfautohint --help

for usage information, or say

  man ttfautohint

to read its manual page.

A GUI to the library is `ttfautohintGUI'; it uses the Qt4 framework.  The
compilation of this application can be disabled with the `--without-qt'
configuration option.


Version 1.7 (2017-Aug-26)

  * Support for Adlam, Avestan, Bamum, Buhid, Unified Canadian Syllabics,
    Carian, Chakma, Coptic, Cypriot, Deseret, Glagolitic, Gothic, Kayah Li,

    Sundanese, Tai Viet, Tifinagh, and Vai scripts.

    Note that the used blue zone characters might not be optimal.  Please
    report any problems so that I can fix issues!

  * Option `--fallback-stem-width` now works for non-symbol fonts also, as

  * TrueType bytecode generated by ttfautohint now correctly supports most
    recent MS interpreter versions.

  * A bug with bytecode for composite glyphs with composite subglyphs is now
