I wrote the below code

    AssertError(LookupError, codecs.lookup_error, 'blah    garbage    xyz')
    def garbage_error1(someError):
        pass
    codecs.register_error('blah    garbage    xyz', garbage_error1)
    AreEqual(codecs.lookup_error('blah    garbage    xyz'), garbage_error1)
    def garbage_error2(someError):
        pass
    codecs.register_error('some    other', garbage_error2)
    AreEqual(codecs.lookup_error('some    other'), garbage_error2)
