+ If *value* is a unicode string then other Unicode decimal digits
+ are also permitted where ``digit`` appears above. These include

+ Arabic-Indic and Devanāgarī digits) along with the fullwidth digits
+ ``u'\uff10'`` through ``u'\uff19'``.

digits, and an integer exponent. For example, ``Decimal((0, (1, 4, 1, 4), -3))``
