Hello,

I would say that when you press the minus key, your operating system doesn't 
encode the standard (ASCII) minus character, but some fancy character, which 
Python cannot interpret.

More precisely, I suspect you are unsing Windows with codepage 1252 (latin 1). 
With this encoding, you have 2 kinds of minus signs: the standard (45th 
character, in hex '\x2d') and the non-standard (150th character, in hex '\x96').
