PyLocale_setlocale in Modules/_localemodule.c is incorrectly passing the locale as a UTF-8 string ("z") instead of using the codepage of the current locale. 

As you can see below "å" is passed as the UTF-8 string "\xc3\xa5":

    >>> locale._setlocale(locale.LC_TIME, 'Norwegian Bokmål_Norway.1252')

The CRT's setlocale works fine when passed the locale string encoded with codepage 1252:

    >>> msvcr100 = ctypes.CDLL('msvcr100')
    >>> msvcr100.setlocale.restype = ctypes.c_char_p
    >>> loc_no = 'Norwegian Bokmål_Norway.1252'.encode('1252')
    >>> msvcr100.setlocale(locale.LC_TIME, loc_no)
    b'Norwegian Bokm\xe5l_Norway.1252'
