Comment (by darkfate):

 Well, the sanitize_user function allows for a space, so it is possible to
 have the space in front since it's not doing trim.


 {{{
         $username = preg_replace('|%([a-fA-F0-9][a-fA-F0-9])|', '',
 $username);
         $username = preg_replace('/&.+?;/', '', $username); // Kill
 entities
 }}}
