"""
An alternate implementation of Python's stdlib `urllib.urlencode
function <http://docs.python.org/library/urllib.html>`_ which
accepts unicode keys and values within the ``query``
dict/sequence; all Unicode keys and values are first converted to
UTF-8 before being used to compose the query string.
The value of ``query`` must be a sequence of two-tuples
representing key/value pairs *or* an object (often a dictionary)
with an ``.items()`` method that returns a sequence of two-tuples
representing key/value pairs.
For minimal calling convention backwards compatibility, this
version of urlencode accepts *but ignores* a second argument
conventionally named ``doseq``. The Python stdlib version behaves
differently when ``doseq`` is False and when a sequence is
presented as one of the values. This version always behaves in
the ``doseq=True`` mode, no matter what the value of the second
argument.
See the Python stdlib documentation for ``urllib.urlencode`` for
more information.
