UTF-8 Reverse

Source code available
Well, this is a basic function I came up with, it reverses UTF-8 encoded strings around..
Because UTF-8 encoded characters use more than 1 byte, simply using PHP's strrev(); did not do the trick.
Obviously if you look at the source, you can do pretty much whatever you want to the input.. doesn't just have to be reversed.

My UTF-8 Reverse function:	Normal strrev reversed:
؟تحمسول - ！すまいざご - !skrow - !уживанен ябет Я	�تح؅ٳ؈ل� - ��㾁㄁㖁㔁� - !skrow - !�Ѷиванен� �ѱеЂ� ��
