Perhaps something along the lines of:
>>> def encode(source):
... return "".join("\%o" % ord(c) for c in source.encode('utf8'))
...
>>> def decode(encoded):
... bytes = "".join(chr(int(c, 8)) for c in encoded.split('\\')[1:])
... return bytes.decode('utf8')
...
>>> encode(u"Í")
'\\303\\215'
>>> print decode(_)
Í
>>>
