Go to the Persian page (first language link) and the very top left link below title (tiny font) of the languages has German in Farsi.
From memory, the next is Arabic, then Turkish, next is Urdu and the last is German.
Ok, when I go to the Persian page, very top left for languages, I get English, Urdu and Arabic, that's all. Have a look now yourself, if you get additional language options, then I don't know why I'm not getting them.
Btw, this is one related thing I just saw on the site in Persian, but you're right it doesn't seem to be related to the English article in this thread?

Yeah, interesting. The English article seems to be for Western consumption.
