note 115441 added to migration54.incompatible

If you have content that is not 100% UTF-8 then TAKE NOTE: Starting in PHP 5.4 htmlspecialchars() and htmlentities() assume charset=UTF-8 by default AND WILL RETURN BLANK IF YOUR INPUT IS NOT VALID UTF-8. So if you have a lot of function calls that look like this: <?php echo htmlspecialchars($input); // or echo htmlentities($input); ?> i.e. no charset and no flags -- and $input is ISO-8859 (or anything else apart from 7-bit ASCII or UTF-8) -- then PHP 5.4 and 5.5 will return an empty string, and you will be surprised and probably unhappy. This is apparently a feature, not a bug. ---- Server IP: 64.68.201.35 Probable Submitter: 99.233.236.58 ---- Manual Page -- http://php.net/manual/en/migration54.incompatible.php Edit -- https://master.php.net/note/edit/115441 Del: integrated -- https://master.php.net/note/delete/115441/integrated Del: useless -- https://master.php.net/note/delete/115441/useless Del: bad code -- https://master.php.net/note/delete/115441/bad+code Del: spam -- https://master.php.net/note/delete/115441/spam Del: non-english -- https://master.php.net/note/delete/115441/non-english Del: in docs -- https://master.php.net/note/delete/115441/in+docs Del: other reasons-- https://master.php.net/note/delete/115441 Reject -- https://master.php.net/note/reject/115441 Search -- https://master.php.net/manage/user-notes.php
