I looked at this one more closely. While I cannot understand what it says, It appears that Arabic numerals are used in dates. It looks like Python want be able to deal with those:
.. ValueError: time data '١٩٩٩/١٠/٢٩' does not match format '%Y/%m/%d'
datetime.datetime(1999, 1, 1, 0, 0)
which further suggests that support of such numerals is accidental.
As I think more about it, though I am becoming less avert to accepting these numerals for base 10 integers. Integers can be easily extracted from text using simple regex and '\d' accepts all category Nd characters. I would require though that all digits be from the same block, which is not hard because Unicode now promises to only have them in contiguous blocks of 10. This rule seems to address some of security issues because it is unlikely that a system that can display some of the local digits would not be able to display all of them properly.
I still don't think it makes any sense to accept them in float().
