Fixed #5846 -- Bullet-proofed the default timezone encoding test.

from datetime import timedelta, tzinfo

from django.utils.encoding import smart_unicode

try:

    DEFAULT_ENCODING = locale.getdefaultlocale()[1] or 'ascii'

except:

    # Any problems at all determining the locale and we fallback. See #5846.

    DEFAULT_ENCODING = 'ascii'

class FixedOffset(tzinfo):

    "Fixed offset in minutes east from UTC."
