note 107498 added to reference.pcre.pattern.modifiers

If the _subject_ contains utf-8 sequences the 'u' modifier should be set, otherwise a pattern such as /./ could match a utf-8 sequence as two to four individual ASCII characters. It is not a requirement, however, as you may have a need to break apart utf-8 sequences into single bytes. Most of the time, though, if you're working with utf-8 strings you should use the 'u' modifier. If the subject doesn't contain any utf-8 sequences (i.e. characters in the range 0x00-0x7F only) but the pattern does, as far as I can work out, setting the 'u' modifier would have no effect on the result. ---- Server IP: 69.147.83.197 Probable Submitter: 115.64.131.178 ---- Manual Page -- http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php Edit -- https://master.php.net/note/edit/107498 Del: integrated -- https://master.php.net/note/delete/107498/integrated Del: useless -- https://master.php.net/note/delete/107498/useless Del: bad code -- https://master.php.net/note/delete/107498/bad+code Del: spam -- https://master.php.net/note/delete/107498/spam Del: non-english -- https://master.php.net/note/delete/107498/non-english Del: in docs -- https://master.php.net/note/delete/107498/in+docs Del: other reasons-- https://master.php.net/note/delete/107498 Reject -- https://master.php.net/note/reject/107498 Search -- https://master.php.net/manage/user-notes.php
