For the development of HarfBuzz, the Microsoft shaping technology, Uniscribe, as a widely used and tested shaper is used as more-or-less OpenType reference implementation and that specially is important where OpenType specification is or wasn't that clear. For having access to Uniscribe on Linux/macOS these steps are recommended:
You want to follow the 32bit instructions. The 64bit equivalents are included for reference.
dnf install wine.
dnf install mingw32-gcc-c++
dnf install mingw64-gcc-c++
apt install g++-mingw-w64
brew install mingw-w64
If you have drank the
meson koolaid, look at
.ci/build-win32.sh to see how to invoke
meson now, or just run that script. Otherwise, here's how to use the old trusty autotools instead:
a) Install dependencies.
dnf install mingw32-glib2 mingw32-cairo mingw32-freetype
dnf install mingw64-glib2 mingw64-cairo mingw64-freetype
NOCONFIGURE=1 ./autogen.sh && mkdir winbuild && cd winbuild
Now you can use
(cd win32build/util && wine hb-shape.exe) but if you like to shape with the Microsoft Uniscribe:
Bring a 32bit version of
usp10.dll for yourself from
C:\Windows\SysWOW64\usp10.dll of your Windows installation (assuming you have a 64-bit installation, otherwise
C:\Windows\System32\usp10.dll) that it is not a DirectWrite proxy (for more info). Rule of thumb, your
usp10.dll should have a size more than 500kb, otherwise it is designed to work with DirectWrite which Wine can't work with its original one. You want a Uniscribe from Windows 7 or older.
Put the DLL in the folder you are going to run the next command,
WINEDLLOVERRIDES="usp10=n" wine hb-shape.exe fontname.ttf -u 0061,0062,0063 --shaper=uniscribe
abc, use test/shaping/hb-unicode-decode to generate ones you need)
