Accepts a UTF-8 string and returns the address of the next character.
#include <utf8.h>
utf8_t *utf8next (
const utf8_t *string);
(IN) Points to the string to start with.
Returns the address of the character next in the specified string.
From the character pointed to by the string parameter, utf8next returns the address of the first byte of the subsequent character, if there is one. The returned address might point beyond the end of the string, especially if the string was badly formed.
