Apparently that documentation is simply wrong. The actual definition of what 'int' handles is *different* from what the parser handles. I think that difference must constitute a bug (not just a doc bug), but I'm not sure if it is something that we want to fix (changing the parser).
I think the *operational* definition of int conversion for both is the same as for isdigit in python3 (https://docs.python.org/3/library/stdtypes.html#str.isdigit). (The python2 docs just say '8 bit strings may be locale dependent', which means the same thing but is less precise).
File "<stdin>", line 1
SyntaxError: invalid character in identifier
The above behavior discrepancy doesn't apply to python2, since in python2 you can't use unicode in integer literals.
So, this is a bit of a mess :(.
The doc fix is simple: just replace the mention of integer literal with a link to isdigit, and fix the python2 isdigit docs to match python3's.
