You can allways add the Czech Language if it's availabe at CM7, although, I'm not sure how.
It's a bit tricky, you have to add the languages to the major system apps, I have a list from miui roms of the files that need change, but I haven't got one for CM7 roms, I'm just going with the gut.So far I have 4 system apk's changed, most of my 2.3.7 installation is in portuguese now. I'm using the lang files from the cm7.2 RC blade rom, no problems so far.
After I figure out all the apk's that need change, I'll just add the other languages. So far we need portuguese, czech and turquish. I could put all the languages but I think it's better just put the ones that are needed by most users to keep the rom slim and clean
Btw, just out of curiosity since I changed most of my rom installation already, do you guys have all the languages on the keyboard dictionary?
