note 108579 added to function.mb-check-encoding

The issue whereby mb_check_encoding($string,'UTF-8') falsely returns true for invalid UTF8 byte sequences was resolved somewhere between PHP 5.2.0 and 5.2.6 The following equivalence seems to work in PHP 5.2.0 and 5.1.6 $valid_utf8 = (@iconv('UTF-8','UTF-8',$string) === $string); (with apologies for the @) ---- Server IP: 94.76.225.145 Probable Submitter: 83.244.193.82 ---- Manual Page -- http://www.php.net/manual/en/function.mb-check-encoding.php Edit -- https://master.php.net/note/edit/108579 Del: integrated -- https://master.php.net/note/delete/108579/integrated Del: useless -- https://master.php.net/note/delete/108579/useless Del: bad code -- https://master.php.net/note/delete/108579/bad+code Del: spam -- https://master.php.net/note/delete/108579/spam Del: non-english -- https://master.php.net/note/delete/108579/non-english Del: in docs -- https://master.php.net/note/delete/108579/in+docs Del: other reasons-- https://master.php.net/note/delete/108579 Reject -- https://master.php.net/note/reject/108579 Search -- https://master.php.net/manage/user-notes.php
