 Honestly I'm not sure if I do :-/ , I have already enough KDE work. The data 
structures of fontconfig seem more complicated than the XIM data, and 
moreover if I comprehend it correctly this data can be modified at runtime in 
the app. That looks more like a complete rewrite of a part of fontconfig to 
me, and that'd be probably better be done by somebody who's not completely 
clueless about it (hmm, does that include also somebody else than you?). Can 
you estimate the extent of work this would require?
