Note the gaps before several of the byte entries above marked by '*'. These are
caused by legal UTF-8 avoiding non-shortest encodings: it is technically
possible to UTF-8-encode a single code point in different ways, but that is
explicitly forbidden, and the shortest possible encoding should always be used
(and that is what Perl does).

ccccbbbbbbaaaaaa 1110cccc 10bbbbbb 10aaaaaa
