There's a bug currently with some patch iterations flying around:
http://bugzilla.gnome.org/show_bug.cgi?id=499650. I can't speak for John or Gabriel, but it looks like they're hammering out details right now that will properly fix it soon.
You can CC yourself to be notified of updates, and I'm guessing they will request people to test it if they need any help that way.
I'm not sure about the case of other languages, but it's certainly a concern. If I recall, it was addressed there? But I don't have time to review the bug's comments now.
