If you always want characters, never bytes, then always use mb_strlen().
It works with whatever the internal-encoding is set to.

You can also set mbstring.func_overload to have strlen() become an alias
for mb_strlen(), so you can continue to write strlen() everywhere. (It
will also then use multi-byte versions of the regex functions.)
