Cyrillic characters support

[tvardero]

Please add support for cyrillic characters

[pkhead]

im pretty sure it's based off the font file you use. since you can use a custom font, probably download one (or copy one from your system) and put it into... config/fonts, i think? then in preferences there's some way of changing which font it uses.

Please add Fairfax font (OFL license, Free for commercial use) as second pre-installed font and make it default for new installations. It looks the same as ProggyClean (pixelated monospace), and has support of cyrillic.

---

Also, as third option, please add Fira Code (OFL-1.1 license). It is not pixalated, but also monospaced and has support for large variety of characters.

Unfortunatelly, installing different font (FiraCode-Light.ttf from Fira Code) did not resolve the issue.

You can use this sentense as test for cyrillic characters (ukraininan):
Добрі вісті не лежать на місці. The quick brown fox jumps over the lazy dog. абвгґдеєжзиіїйклмнопрстуфхцчшщьюя АБВГҐДЕЄЖЗИІЇЙКЛМНОПРСТУФХЦЧШЩЬЮЯ abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ 0123456789 .,!?_-+=@$%&

Since project uses imgui.net, I suspect this is somewhere related to configuration of it.

var font = io.Fonts.AddFontFromFileTTF(fullFilePath, fontSize * Boot.WindowScale);

Needs to include glyph range:

var range = io.Fonts.GetGlyphRangesCyrillic();
var font = io.Fonts.AddFontFromFileTTF(fullFilePath, fontSize * Boot.WindowScale, null, range);
