New submission from Jim Jewett <[email protected]>:
Python identifiers are in NFKC form; string method .isidentifier() returns true
on strings that are not in that form. In some contexts, these non-canonical
strings will be replaced with their NFKC equivalent, but in other contexts
(such as the builtins hasattr, getattr, delattr) they will not.
>>> cha=chr(170)
>>> cha
'ª'
>>> cha.isidentifier()
True
>>> uc.normalize("NFKC", cha)
'a'
>>> obj.ª = 5
>>> hasattr(obj, "ª")
False
>>> obj.a
5
