I don't know much about Ireland, maybe it's not that sensitive an issue there. So how about this: what's the correct flag to show for Arabic in Israel?

Last time I fiddled with some automated kiosk at Ben Gurion airport I noticed they used a Jordanian flag for Arabic. That's an interesting choice, because if I had to guess most of the people choosing Arabic at that kiosk would not choose that as their flag.

So have another example: if you were to translate your application into Tibetan (for some reason), what flag would you use for it?

(The Tibetan flag is literally illegal to display in Tibet, as the Chinese government considers it a symbol of the separatist movement. So you probably don't want to use that...)
