strlen() under unicode.semantics

Hi: Enjoyed Andrei's talk at the NYPHP Conference last week about unicode in PHP 6. He mentioned that when unicode.semantics is on, strlen() will return the number of characters rather than the number of bytes, like mb_string() does or strlen() if mbstring.func_overload is on. The hitch here is there are situations where one needs to know how many bytes are in a string. Is there a function I've overlooked that does this or will do this, please?
