Thread:Support/Language with worng name and it's not in CLDR!

Hello, I'm a 'high contributor' of Tunisian Language (working in group to Standardize Tunisian Language), and when I registered in TranslateWiki, I found that Tunisian language has a weird name 'زَوُن' .. it's a name without any meaning, and also, all pages here are RTL, whereas in Incubator it's in LTR (the true one is LTR, because we are 'officially' using Latin script). So, Can anyone here explain to me that? and how can I change it? Also, I can't find Tounsi or even زون in this page: https://git.wikimedia.org/blob/mediawiki%2Fcore.git/master/languages%2fNames.php Can you please explain to me what I must do? Thank you.
