>>> import urllib
>>> urllib.quote("Löblich ähnlich üblich")
'L%C3%B6blich%20%C3%A4hnlich%20%C3%BCblich'
>>> urllib.unquote(_)
'L\xc3\xb6blich \xc3\xa4hnlich \xc3\xbcblich'
>>> print _
Löblich ähnlich üblich

If you care about the encoding you have to encode/decode explicitly:

>>> urllib.quote(u"Löblich ähnlich üblich".encode("latin1"))
'L%F6blich%20%E4hnlich%20%FCblich'
>>> urllib.unquote(_).decode("latin1")
u'L\xf6blich \xe4hnlich \xfcblich'
