That's the problem. We would need a very diverse font that covers a large variety of languages if we want everyone in the game to be able to type in their own language. As for the staff topic, you not only need to find someone that is exceptional with English AND another language, but you need to find someone that also is mature enough to be staff. It kind of drains out the choices. Also, you would need a lot of different language oriented staff to cover the main languages. Essentially, English is looked upon as the international language bridge for most people precisely because of this logistic problem.
