Clarify that, unlike C-strings, PHP-strings are properly binary safe, i.e. not internally null-terminated, and can include embedded \0. One might otherwise wrongly expect that, for example strlen("hello\0world") would be 5. 2. The reference to PHP's strings not being natively Unicode is a bit confusing: a string is just a sequence of bytes, and doesn't, conceptually, even have a character set! UTF-8 is already transparently ASCII compatible as a byte-stream. It's just certain functions (strlen, strtolower etc) that can't cope. [May I suggest a reference to the UTF-8 FAQ: http://www.cl.cam.ac.uk/~mgk25/unicode.html ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55668&edit=1
