1For the development of HarfBuzz, the Microsoft shaping technology, Uniscribe, 2as a widely used and tested shaper is used as more-or-less OpenType reference 3implementation and that specially is important where OpenType specification 4is or wasn't that clear. For having access to Uniscribe on Linux/macOS these 5steps are recommended: 6 71. Install Wine from your favorite package manager. On Fedora that's `dnf install wine`. 8 92. And `mingw-w64` compiler. 10 With `brew` on macOS, you can have it like `brew install mingw-w64`. 11 On Fedora, with `dnf install mingw32-gcc-c++`, or `dnf install mingw64-gcc-c++` for the 12 64-bit Windows. 13 143. Install cross-compiled dependency packages. Alternatively see [^1] below. 15 On Fedora that would be `dnf install mingw32-glib2 mingw32-cairo mingw32-freetype` 16 for 32-bit, or `dnf install mingw64-glib2 mingw64-cairo mingw64-freetype` for 64-bit. 17 185. `NOCONFIGURE=1 ./autogen.sh && mkdir winbuild && cd winbuild` 19 206. Run `../mingw32.sh` for 32-bit build, or `../mingw64.sh` for 64-bit. This configures 21 HarfBuzz for cross-compiling. It enables Uniscribe backend as well. 22 237. `make` 24 25Now you can use hb-shape using `wine util/hb-shape.exe` but if you like to shape with 26the Microsoft Uniscribe, 27 288. Bring a 32bit version of `usp10.dll` for yourself from `C:\Windows\SysWOW64\usp10.dll` of your 29 Windows installation (assuming you have a 64-bit installation, otherwise 30 `C:\Windows\System32\usp10.dll`) that it is not a DirectWrite proxy 31 ([for more info](https://en.wikipedia.org/wiki/Uniscribe)). 32 Rule of thumb, your `usp10.dll` should have a size more than 500kb, otherwise 33 it is designed to work with DirectWrite which Wine can't work with its original one. 34 You want a Uniscribe from Windows 7 or older. 35 36 Put the DLL in the folder you are going to run the next command, 37 389. `WINEDLLOVERRIDES="usp10=n" wine util/hb-shape.exe fontname.ttf -u 0061,0062,0063 --shaper=uniscribe` 39 40(`0061,0062,0063` means `abc`, use test/shaping/hb-unicode-decode to generate ones you need) 41 42 43[^1] Download and put [this](https://drive.google.com/open?id=0B3_fQkxDZZXXbWltRGd5bjVrUDQ) 44 in your `~/.local/i686-w64-mingw32`. Then replace all the instances of 45 `/home/behdad/.local/i586-mingw32msvc` and `/home/behdad/.local/i686-w64-mingw32` 46 with `<$HOME>/.local/i686-w64-mingw32` on that folder. 47 (`<$HOME>` replace it with `/home/XXX` or `/Users/XXX` on macOS) 48 You shouldn't replace the instances of those inside binary files. 49
