Comment (by SergeyBiryukov):

 Please check if the attached plugin works for you.
 The difference is in the regular expression:
 {{{
 $username = preg_replace( '|[^a-z\p{Arabic}0-9 _.\-@]|iu', '', $username
 );
 }}}
 It uses `\p{Arabic}` [http://www.regular-
 expressions.info/unicode.html#script Unicode script].
