Unicode conformance isn't specified in the same way as Decimal
conformance. While there are certain algorithms that can be tested
(e.g. normalization, encoding, decoding), much of the conformance
requirements (AFAIK) are expressed in lots of words about providing
certain facilities etc. I don't actually think putting lots of effort
into this is well-spent; given the mechanical nature of the
translation from the unicode database files into C code (see
Tools/unicode/makeunicodedata.py) a bug in the translation is likely
to result in either bad C code or a systematic error that is easily

No way.

That's the plan.
