* Unicode 3.something introduced a set of codes for language tagging,
but they do not use standard language tags (which are specified using
a subset of US-ASCII), they of course are not available in earlier
versions of Unicode implementations, and they may well have been
withdrawn in Unicode 4.0.
Deprecated, not withdrawn, I believe.
Anyway, they *do* use standard language codes to the best of my knowledge
- they do not define codes of their own. They just shift the encoding of
the tag characters to plane 14.
Doesn't mean it would be wise to use those for IDN, of course.
