Rejecting these is not a bug IMO. Unicode is only defined up to
U+10FFFF. Codepoints above are not valid UTF-8 at all, and in
particular 5/6-byte sequences are never valid UTF-8 (they used to be).
But there are indeed other bugs...

...and also some good catches here! In particular U+110000 should be
rejected.
