A separate plugin is needed because HIM ardcodes the font and that font doesn't support Arabic.

I have to admit that my code is not that good and there's room for improvements. It's also a bit slow but I scratched my itch and it works for me.

What I'd do is to package the Hebrew XML file, depend on him-arabic (From my maemo repository) and execute "him-arabic-register he" in postinst and that's it.

Cheers,
