One would say that there's an option to have two languages known for your character on the entry of the dome, but (hopefully not getting too deep into it) I think that you are very limited to the UE distribution when you simply want to make a believable chatacter from the overseas.
This results in various characters awkwardly not knowing how to talk in their native to the other characters from the same background.
I think letting characters know two languages on the entry (following their background allows it) is going to both eliminate the awkard situation statrd above and make people use languages other than English more in game.
