just installed fireflysung.tcz
after restart seamonkey browser shows japanese and russian too
and maybe other apps
sure, for example in texteditor geany > view font : select the chinese one (it works for me)
/usr/local/share/locale/zH_CN/LC_MESSAGES/geany.mo exists (geany-locale.tcz)
if you have set the locale
then geany will work in chinese user interface
