@Amire80: In the "ULS for editors" section, it says you can style text with different fonts, but the example doesn't work. Is that feature completely broken or just that font? Kaldari (talk) 18:25, 18 December 2017 (UTC)

It works at w:en:User:Amire80/Latf. Did you enable webfonts? Click on the gear icon -> Fonts -> Download fonts when needed. Unfortunately it cannot be on by default.
Nope, didn't do that! I'll add that to the documentation.
