Oh, I forgot to mention, this works back to at least Python 2.4, provided 
you remember to use Unicode strings rather than bytes:


py> b = '۳۴۵۵'  # This fails.
py> int(b)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '\xdb\xb3\xdb\xb4\xdb
\xb5\xdb\xb5'

py> s = u'۳۴۵۵'  # This works.
py> int(s)
3455
