C's strlen() returning the number of bytes is perfectly fine. But in
PHP I don't need malloc(), and I have not yet found a reason to pick out
single bytes out of a *character* string (as opposed to a *byte* string,
which are different concepts IMO), except for emulating some UTF-8 aware
functionality.

Consider that programming in PHP happens on a higher level than in C
(e.g. one doesn't need to allocate heap memory, nor does one have to
free it). This results in the ability to write programs faster, that
run slower. But the fact, that PHP's string functions work on bytes
(opposed to characters), partially annihilates the advantage[1]. That
is particularly sad, as PHP has its strengths for web development and
UTF-8 is the de facto standard for the web.

[1] Say, I need a wordwrap() for sending UTF-8 encoded emails. Sigh...
BTW: <http://www.php.net/manual/en/function.wordwrap.php> says:

| wordwrap — Wraps a string to a given number of characters

what's obviously wrong; it wraps a string to a given number of bytes.
