IDNA2008 test vectors

[Mark Davis ☕]

That looks like a bug, I'll check it out.

The ideographic period is allowed under IDNA2003, but should be mapping to
".". (Also, in the next revision, there will be a field that indicates that
the input isn't allowed under IDNA2008, so that people can distinguish them.
