Good to know they use fontconfig more or less properly
For those trying to figure this out, you might also want to check the fontconfig stuff in the K3 fonts hack (I went with a config a bit more intrusive, but the simple match->assign on the default font family used here is a neat idea
I still plan on checking this (ie. Fonts on the Touch) out in detail, as soon as they're available on the French KS... -_-".
One other thing to check: If you use a font with bigger glyphs, and a part of the UI text overruns, does it still horribly breaks the UI, or is the text cropped?
