note 113919 added to function.mb-check-encoding

Unlike other comments suggest, there's no need to serialize a string to use preg_match's "u" modifier for testing if a string is valid UTF-8. You can just use <?php function is_utf8($str) { return (bool) preg_match('//u', $str); } ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/function.mb-check-encoding.php Edit -- https://master.php.net/note/edit/113919 Del: integrated -- https://master.php.net/note/delete/113919/integrated Del: useless -- https://master.php.net/note/delete/113919/useless Del: bad code -- https://master.php.net/note/delete/113919/bad+code Del: spam -- https://master.php.net/note/delete/113919/spam Del: non-english -- https://master.php.net/note/delete/113919/non-english Del: in docs -- https://master.php.net/note/delete/113919/in+docs Del: other reasons-- https://master.php.net/note/delete/113919 Reject -- https://master.php.net/note/reject/113919 Search -- https://master.php.net/manage/user-notes.php
