    Python 3: skip test_json_with_utf8 on Py3

    The last skipped unit test should indeed be skipped: it does not make
    sense to run it with Python 3.

    $ python 2
    >>> import json; json.dumps({'a': u'\xe9'.encode('utf-8')})
    '{"a": "\\u00e9"}'

    $ python3
    >>> import json; json.dumps({'a': u'\xe9'.encode('utf-8')})
    Traceback (most recent call last):
      ...
      File "/usr/lib64/python3.4/json/encoder.py", line 173, in default
        raise TypeError(repr(o) + " is not JSON serializable")
    TypeError: b'\xc3\xa9' is not JSON serializable

    In Python 2, the JSON encoder function to encode a string begins with
    a magic test to convert UTF-8 encoded string to Unicode:

        if isinstance(s, str) and HAS_UTF8.search(s) is not None:
            s = s.decode('utf-8')

    This trick is gone in Python 3:
