Ah, that makes sense.  Some simple testing (thanks, unicodedata
module) supports your conjecture.

It's not a particularly big deal so not really worth the brain-cycles
to add support for them.  Just upon hearing "Python's int() does
smart things with Unicode characters", those were some of my first
characters to try.  The failure struck me as odd until you explained
the simple difference.
