Ezio Melotti <[email protected]> added the comment:
I think float() should support non-ascii digits but I agree that it would be
better to avoid UnicodeErrors and convert them to ValueErrors so that
>>> float('١٢٣٤.٥٦')
1234.56
and
>>> float('½')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid literal for float(): ½
I.e. float should do the C equivalent of:
try:
s = arg.encode('decimal')
except UnicodeEncodeError:
raise ValueError('Invalid liter for float(): {}'.format(arg))
Note that int() and Decimal() supports non-ascii chars too.
