py3: make sure we return strings from __str__ and __repr__

On Python 3:

>>> class abc:
...     def __repr__(self):
...             return b'abc'
...
>>> abc()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: __repr__ returned non-string (type bytes)

>>> class abc:
...     def __str__(self):
...             return b'abc'
...
>>> str(abc())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: __str__ returned non-string (type bytes)

So the __str__ and __repr__ must return strings.
