For having access to Uniscribe on Linux/macOS these +steps are recommended: + +1. Install Wine from your favorite package manager. On Fedora that's `dnf install wine`. + +2. And `mingw-w64` compiler. + With `brew` on macOS, you can have it like `brew install mingw-w64`. + On Fedora, with `dnf install mingw32-gcc-c++`, or `dnf install mingw64-gcc-c++` for the + 64-bit Windows. + +3. Install cross-compiled dependency packages. Alternatively see [^1] below. + On Fedora that would be `dnf install mingw32-glib2 mingw32-cairo mingw32-freetype` + for 32-bit, or `dnf install mingw64-glib2 mingw64-cairo mingw64-freetype` for 64-bit. + +5. `NOCONFIGURE=1 ./autogen.sh && mkdir winbuild && cd winbuild` + +6. Run `../mingw32.sh` for 32-bit build, or `../mingw64.sh` for 64-bit. This configures + HarfBuzz for cross-compiling. It enables Uniscribe backend as well. + +7. `make` + +Now you can use hb-shape using `wine util/hb-shape.exe` but if you like to shape with +the Microsoft Uniscribe, + +8. 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](https://en.wikipedia.org/wiki/Uniscribe)). + 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, + +9. `WINEDLLOVERRIDES="usp10=n" wine util/hb-shape.exe fontname.ttf -u 0061,0062,0063 --shaper=uniscribe` + +(`0061,0062,0063` means `abc`, use test/shaping/hb-unicode-decode to generate ones you need) + + +[^1] Download and put [this](https://drive.google.com/open?id=0B3_fQkxDZZXXbWltRGd5bjVrUDQ) + in your `~/.local/i686-w64-mingw32`.
