But mb_strtolower() und mb_strtoupper() simply return the ASCII uppercase or lowercase counterparts. You get the correct result with: setlocale(LC_ALL, 'tr_TR'); echo strtoupper('i'); echo strtolower('I'); But the wrong results with: echo mb_strtoupper('i', 'iso-8859-9'); echo mb_strtolower('I', 'iso-8859-9'); ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29955&edit=1
