locale.setlocale() does not work if you pass it a ``unicode`` object instead of a ``str`` (, line 576):

    ``if locale and type(locale) is not type(""):``

Maybe it would be better to do a check like this?

    ``if locale and not isinstance(locale, basestring):``

In particular, this can bite you if you use the ``unicode_literals`` future import, displaying a not-so-helpful error message ("ValueError: too many values to unpack" in _build_localename).

Thanks for the report.  There was a lengthy discussion of this behavior a few years ago in Issue3067.  At that time it was decided not to change this behavior for 2.7.  I'm not sure if the __future__ "unicode_literals" was considered then, however you can work around it by using the b"" literal syntax:

    locale.setlocale(locale.LC_ALL, b'POSIX')
