You do not provide an encoding so it depends on the configuration. I suggest to provide the encoding argument to the function calls. $mb_test = mb_strtoupper($mb_test, 'UTF-8'); ------------------------------------------------------------------------ [2017-05-31 10:55:21] spam2 at rhsoft dot net Description: ------------ bad enough that mb_strtoupper() don't work at all but that mb_strtolower() destroys the string is a no-go [harry@rh:/downloads]$ cat test.php <?php $mb_test = utf8_encode(chr(252) . chr(246) . chr(228)); echo "$mb_test\n"; $mb_test = mb_strtoupper($mb_test); echo "$mb_test\n"; $mb_test = mb_strtolower($mb_test); echo "$mb_test\n"; [harry@rh:/downloads]$ php test.php üöä üöä ������ ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74678&edit=1
