Wrong language display and language name

Hello, I contacted "many" people to tell them about this bug but I can't get an Answer. The problem first is with language name, it's absolutely called "Tounsi", not "زَوُن". The second problem is with writing direction, it's LTR because we are standardizing Written Tunisian using Latin script. And of course we are using that standardization on Wikipedia. Please fix it.

Ah! and numbers, we don't use Eastern Arabic numbers, we use the normal numbers.
