isdigit() includes decimal digits plus other characters that have a digit value:

    >>> print u'\N{superscript two}'
    ²
    >>> unicodedata.digit(u'\N{superscript two}')
    2

However, int(u'\N{superscript two}') raises a ValueError. int() only
accepts the subset of digits that are isdecimal().
