Your __str__ and __repr__ methods don't return strings.  You should
encode your unicode to the encoding you want before you try to print it.

class A(object):
    def __unicode__(self):
        return u"©au"

    def get_utf8_repr(self):
        return self.__unicode__().encode('utf-8')

    def get_koi8_repr(self):
        return self.__unicode__().encode('koi-8')

    __str__ = __repr__ = self.get_utf8_repr
