After trying another accounts , I found MOST users with special characters in their Login_Name cannot login !

I don't know why , can somebody tell me what to do ?
UBB6 is OK , But after upgrading , this is frustrating...

My DB encoding is UTF-8 , so , these special characters are saved in UTF8 format.

Does it related to start_page.inc.php or do_login() in ubbthreads.inc.php ? Is there any encoding trick inside ?
