My first contribution! After endless hours of experimenting, I found the only combination of fonts that would allow the NIT (I own both n770 and n800) to display both Chinese and Japanese correctly on the same machine: kochi-gothic for Japanese and simhei for Chinese. The former I got when installing the maemo Japanese support (I then uninstalled the kochi-mincho that came with it). The latter I copied from my Win XP to /usr/share/fonts. I am still having problem with Korean display though.
