I suggest to correct the examples; those tests really test something
else. UTF-8 is not part of IDNA, and any self-respecting UTF-8 library
should have separate test cases, eg. the ones from RFC 2279.

(and yes, I probably found all such errors, as I literally copied the
test cases into my Python IDNA test suite).
