I guess this issue poped-up in the pass.
could not find an answer for it in the forum..so here it is again

Is there a way to use none english letters for username?
I get many complains from users regarding that issue

It starts with registering website, and continues with working with website (user search etc.)

Using "Real Name" field  is not an option.
since website operate as dating website, people prefer to keep their real name hidden.

anyone have a solution?
