Ok i asked a friend of mine to login with facebook and his name has ğ,ö,ç,ü,İ characters and is longer than 20 chars.
What happened is: the name got cut in 20th char and the username has these characters now. Is there a way to replace these chars if the user is coming from facebook? Because when the user tries to look at his profile it gives an error saying there is no user like this. So i changed the chars in database in order to fix this. It would be great while creating username all chars are converted or replaced by english chars just incase.
Also i changed the handle field that keeps the username to 50 chars in qa_user table will this have a negative on anything?
