Finds the previous UTF-8 character in the string before 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 p might be the first
character of the string, you must use GLib.utf8_find_prev_char
instead.
