note 124581 added to function.mb-strlen

It may not be clear whether PHP actually supports utf-8, which is the current de facto standard character encoding for Web documents, which supports most human languages. The good news is: it does. I wrote a test program which successfully reads in a utf-8 file (without BOM) and manipulates the characters using mb_substr, mb_strlen, and mb_strpos (mb_substr should normally be avoided, as it must always start its search at character position 0). The results with a variety of Unicode test characters in utf-8 encoding, up to four bytes in length, were mostly correct, except that accent marks were always mistakenly treated as separate characters instead of being combined with the previous character; this problem can be worked around by programming, when necessary. ---- Server IP: 45.112.84.4 Probable Submitter: 38.142.137.34 (proxied: 98.2.238.89) ---- Manual Page -- http://php.net/manual/en/function.mb-strlen.php Edit -- https://master.php.net/note/edit/124581 Del: integrated -- https://master.php.net/note/delete/124581/integrated Del: useless -- https://master.php.net/note/delete/124581/useless Del: bad code -- https://master.php.net/note/delete/124581/bad+code Del: spam -- https://master.php.net/note/delete/124581/spam Del: non-english -- https://master.php.net/note/delete/124581/non-english Del: in docs -- https://master.php.net/note/delete/124581/in+docs Del: other reasons-- https://master.php.net/note/delete/124581 Reject -- https://master.php.net/note/reject/124581 Search -- https://master.php.net/manage/user-notes.php
