Quests requiring languages besides Common?

[Axlrose]

I have always wondered if there are (or were) to be quests in the game that required the player to talk to the non playing character (or target monster) proficiently in a language other than Common? The player is allowed to learn all these different languages, but short of role playing, they do not seem to have a purpose.

Is there something in the game that perhaps has been missed all this time? Yes, the code has (probably) been reviewed forwards and backwards, but still...

Thanks!
