Sure, if we code it in Python, supporting it will by much easier:

def normalize_digits(s):
    digits = {m.group(1) for m in re.finditer('(\d)', s)}
    trtab = {ord(d): str(unicodedata.digit(d)) for d in digits}
    return s.translate(trtab)

>>> normalize_digits('١٢٣٤.٥٦')
'1234.56'

I am not sure this belongs to the locale module, however.  It seems to
me, something like 'unicodealgo' for unicode algorithms would be more
appropriate.
