Stephan Houben noticed that Python apparently allows identifiers to be
keywords, if you use Unicode "mathematical bold" letters. His
explanation is that the identifier is normalised, but not until after
keywords are checked for. So this works:

class Spam:
     locals()['if'] = 1


Spam.𝐢𝐟    # U+1D422 U+1D41F
# returns 1


Of course Spam.if fails with SyntaxError.

Should this work? Is this a bug, a feature, or an accident of
implementation we can ignore?

Voting for bug:
Either those identifiers should be considered equal, or they shouldn't. They can't be considered "partially" equal.
