Well, one problem is that it messes up character counts. Suppose
you're aware that the thousands separator might be a single multibyte
character, and you want to produce a unicode result that's zero-padded
to a width of 6. There's currently no sensible way of doing this that
I can see:
format(Decimal('1000'), '06n').decode('utf-8') gives a string of length 5
format(Decimal('1000'), u'06n') fails with a UnicodeDecodeError.
