According to What language(s) should we use for the site? and Question bodies in other languages it seems to have been agreed upon that questions in Russian are OK. However, it seems that the SE itself doesn't allow that. I tried to post a question in Russian with a Russian title and the system rejected it as "It does not meet our quality standards." I think it's because all characters were in cyrillic. Can anyone please comment on this?
In order to reproduce the problem, try to ask a question with the following title
Заглавие на русском языке
and the following body
Несмотря на то, что в мете было установлено, что вопросы можно задавать на русском, сам сайт не позволяет этого делать. Почему это так?
This wasn't my actual question, I just thought the rejection was due to Russian, so I made up this fake question that clearly reproduces the problem.
Update: seems that the problem occurs only when the title is in Russian in its entirety.
Update: I requested the feature at https://meta.stackexchange.com/questions/136457/can-we-please-allow-russian-titles-in-russian-stackexchange-com
