Finds the start of the next UTF-8 character in the string after p.
p does not have to be at the beginning of a UTF-8 character. No check
is made to see if the character found is actually valid other than
it starts with an appropriate byte.
If end is NULL, the return value will never be NULL: if the end of the
string is reached, a pointer to the terminating nul byte is returned. If
end is non-NULL, the return value will be NULL if the end of the string
is reached.
Parameters
p: string
a pointer to a position within a UTF-8 encoded string
end: string|null
a pointer to the byte following the end of the string, or NULL to indicate that the string is nul-terminated
Returns string|null
a pointer to the found character or NULL if end is set and is reached
