[Diverting to python-ideas, since this isn't as clear-cut as you think.] Why exactly is that expected behavior? What's the use case? (Surely you don't have a keyboard that generates \u2212 when you hit the minus key? :-)
Is there a Unicode standard for parsing numbers? IIRC there are a variety of other things marked as "digits" in the Unicode standard -- do we do anything with those? If we do anything we should be consistent. For now, I think we *are* consistent -- we only support the ASCII representation of numbers. (And that's the only representation we generate as output as well -- think about symmetry too.)
