note 113081 added to function.mb-strtoupper

mb_strtoupper() will not convert the German "ß" character into its (relatively new) uppercase form ("ẞ"). mb_strtolower() will, however, convert the uppercase form into a lowercase "ß". (tested with PHP 5.5.0) "SS" is still the most common uppercase presentation of "ß". If you want this, you'll have to do it manually: <?php mb_internal_encoding("UTF-8"); echo mb_strtoupper("Maß\n"); // "MAß" echo mb_strtolower("MAẞ\n"); // "maß" echo mb_strtoupper(str_replace("ß", "SS", "Maß\n")); // "MASS" ?> ---- Server IP: 192.35.244.50 Probable Submitter: 213.47.132.228 ---- Manual Page -- http://php.net/manual/en/function.mb-strtoupper.php Edit -- https://master.php.net/note/edit/113081 Del: integrated -- https://master.php.net/note/delete/113081/integrated Del: useless -- https://master.php.net/note/delete/113081/useless Del: bad code -- https://master.php.net/note/delete/113081/bad+code Del: spam -- https://master.php.net/note/delete/113081/spam Del: non-english -- https://master.php.net/note/delete/113081/non-english Del: in docs -- https://master.php.net/note/delete/113081/in+docs Del: other reasons-- https://master.php.net/note/delete/113081 Reject -- https://master.php.net/note/reject/113081 Search -- https://master.php.net/manage/user-notes.php
