>We could perhaps guard the "generic" fonts by a LANG test and leave the rest

Then, how could one use a particular font over other fonts?
Japanese prefer Japanese font over Chinese font.
I don't know Chinese but I think Chinese prefer Chinese font over Japanese font.

Current workaround most Japanese Ubuntu users take is uninstalling the Chinese font.
Since their problem is, Chinese font is selected over Japanese font.
Other workaround is modifying the 69-language-selector-ja-jp.conf by hand.

We need a font preference setting completely independent from current locale setting.
Just because somebody using en_US.UTF-8 doesn't mean he wish to use random Japanese/Chinese fonts for each CJK characters.
