For example, as far as I can tell, the only way to write code to join a
channel named #tëst (UTF-8 encoded) is:

channel = u'#tëst'
if PY3:
    channel = channel.encode('utf-8')
client.join(channel)

On Python 3, client.join(b'#t\xc3\xab') will try to send JOIN b'#t\xc3\xab',
which is garbage, whereas on Python 2, client.join(u'#t\xebst') will
produce a UnicodeEncodeError.
