I'm trying to reset my password and the security question comes up like this ???μa p??t?? ?at????d???

I have no idea what the question is and I'm trying possible answers with no result. 

I've also tried to fill in the "account verification form" but was in vain too. 

The account's been created many years ago and I don't remember the informaion I povided then.

I need an answer immediately because I want to use my account, the password of which I haven't changed recently!
