This function has two purposes: one is two iterate backwards through a UTF-8
encoded string. Note that it is usually a better idea to iterate forward instead,
since <code>utf8::next</code> is faster. The second purpose is to find a beginning
of a UTF-8 sequence if we have a random position within a string.

case <code>utf8::prior</code> may not detect an invalid UTF-8 sequence in some scenarios:
for instance if there are superfluous trail octets, it will just skip them.
