I don't really like the currently used in-game font(s), and it's quite disappointing that the charset only supports English (as far as I know), considering this is an international open-source game project.
Now, I don't want to complain, but I would like to offer to make new font-files, and a few suggestions:
Use the ISO/IEC 8859-15 charset (without control codes, obviously)
This would cover English, German, French, Italian, Spanish, Portuguese, and 25+ more (Wikipedia).
And there still would be room for 65 Nexuiz-specific special characters/pictograms.
New special characters/pictograms
The current ones appear to be upscaled (and then are downscaled again in-game), several emoticons are covering 2 spots, and there are too many line (-_¯) characters (about 16)
Multiple Fonts
I would be willing to make several different font-files (for example Verdana, URW Gothic, Century Schoolbook,...)
But this would only be useful if it will be possible to set them in the menu.
I made some test files to see how it works (URW Gothic, ISO 8859-15):


I don't really know if there may be (good) reasons to not change the current charset, or fonts, or in any case, who I should adress this to...
That's why I'm posting it here, to find out.
