Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change in a future release of PHP without notice. Be warned and use this function at your own risk.

mb_strlen() returns number of characters in string `str` having character encoding `encoding`. A multi-byte character is counted as 1.

`encoding` is character encoding for `str`. If `encoding` is omitted, internal character encoding is used.
