Try your code with u"abcd\xa1" ... it says it's ASCII.

Suggestions:
   test_ascii = lambda s: len(s.decode('ascii', 'ignore')) == len(s)
or
   test_ascii = lambda s: all(c < u'\x80' for c in s)
or
   use try/except

Also:
    if a == b:
        return True
    else:
        return False
is a horribly bloated way of writing
    return a == b
