clear what it is talking about if you're not a Unicode expert:

You are right, that is clear, thanks :)
Examples:
py> c = '\u2155'
py> print(c)
⅕
py> c.isdecimal(), c.isdigit(), c.isnumeric()
(False, False, True)
py> import unicodedata
py> unicodedata.numeric(c)
0.2
py> c = '\u00B2'
py> print(c)
²
py> c.isdecimal(), c.isdigit(), c.isnumeric()
(False, True, True)
py> unicodedata.numeric(c)
2.0
Perfect explanation, thanks again, Marco
