Xolonium
========

Xolonium is a futuristic typeface, with focus on legibility.
It provides support for Latin, Greek, and Cyrillic glyph sets,
and includes various pictograms and emoticons.

Xolonium originated as a custom font for the open-source game
[Xonotic](https://xonotic.org).


Build
-----

The fonts are compiled with the provided Makefile,
which runs the scripts from the `tools` directory.
FontForge might complain about non-BMP kern pairs,
these are fixed during the build process:

```
make all
```

Fonts can be compiled individually as well:

```
make fonts/ttf/Xolonium-Regular.ttf
```

The generated files can be deleted with:

```
make clean
```
