note 76396 added to function.mb-check-encoding

This function returns true incorrectly sometimes (at least when internal encoding is UTF-8 and encoding being checked for is Windows-1251, and PHP version 4.4.4 on FreeBSD 6.2 STABLE). This bug was not answered in bug reporting yet, so here is a workaround: Instead of checking for this: <?php mb_check_encoding($var, $destination_encoding) ?> check for this: <?php mb_check_encoding($var, $destination_encoding) && mb_substr_count($var, '?', $source_encoding) == mb_substr_count(mb_convert_encoding($var, $destination_encoding, $source_encoding), '?', $destination_encoding) ?> The idea is to count question mark characters ('?') in original value and converted value, because mb_convert_encoding function uses question marks to substitute characters that are not valid in destination encoding. ---- Server IP: 69.147.83.197 Probable Submitter: 77.123.32.227 ---- Manual Page -- http://www.php.net/manual/en/function.mb-check-encoding.php Edit -- https://master.php.net/note/edit/76396 Del: integrated -- https://master.php.net/note/delete/76396/integrated Del: useless -- https://master.php.net/note/delete/76396/useless Del: bad code -- https://master.php.net/note/delete/76396/bad+code Del: spam -- https://master.php.net/note/delete/76396/spam Del: non-english -- https://master.php.net/note/delete/76396/non-english Del: in docs -- https://master.php.net/note/delete/76396/in+docs Del: other reasons-- https://master.php.net/note/delete/76396 Reject -- https://master.php.net/note/reject/76396 Search -- https://master.php.net/manage/user-notes.php
