The int() and float() functions accept, if I'm not mistaken, anything
with Unicode category "Nd" (Number, decimal digit). In your examples,
the fraction (U+215B) is No, and the Roman numerals (U+2168, U+2182)
are Nl, so they're not supported. Adding support for these forms might
be accepted as a feature request, but it's not a bug.
(I may be wrong about the definition being based on category. It may
be based on the "Numeric type" of each character. But again, the
characters that are accepted would be those which have a Digit type,
not merely Numeric, and again, it'd be a feature request to expand
that.)
