* g_utf8_reverse:
* @string: a UTF-8 string.
*
* Reverses a UTF-8 string. The @string must be valid UTF-8 encoded text.
* (Use g_utf8_validate() on all text before trying to use UTF-8
* utility functions with it.)
*
* Note that unlike g_strreverse(), this function returns
* newly-allocated memory, which should be freed with g_free() when
* no longer needed.
*
* Returns: a newly-allocated string which is the reverse of @string.
