I should add you have to have the language installed. The box I'm on right now only has english language enabled so the above does nothing but generate an error and launch app in English.
$ LC_ALL=ru_RU.UTF-8 firefox
(process:12242): Gtk-WARNING **: Locale not supported by C library. Using the fallback 'C' locale.

I'm at work and I don't have any systems with Trinity on them here but this works for standard applications "LC_ALL=ru_RU.UTF-8 firefox" no quotes will launch Firefox in Russian on my system. At least it looks like Russian I don't speak it.
