[issue44981] `module has no attribute` when `__all__` includes certain unicode characters

[Steven D'Aprano]

Eric, I think you may have been too hasty to close this as "not a bug".

It has tripped people up before. See #41542 which has also been closed (I also think prematurely).

We normalise variable names with NFKC, so we should normalise the values in __all__ as well, at least when doing an import.

Note that this is different from #42680 where the right answer is just to document. We shouldn't normalise strings as dict keys.
