[Marc-Andre Lemburg}
It handles surrogates correctly, but rejects isolated ones on input
(easy to fix though) and passes them through on output. As I said
before, surrogate is far from being complete.

Marc-Andre, there is a *bug* in 2.1 encoding isolated high surrogates. I
reported it
and you assigned it to yourself on 23 June. Lookee here:

Python 2.1 (#15, Apr 16 2001, 18:25:49) [MSC 32 bit (Intel)] on win32
Type "copyright", "credits" or "license" for more information.
>>> u'\ud800'.encode('utf-8')
'\xa0\x80' # should be 3 bytes, not 2

While the fix is trivial, IMO an appropriate answer to Guido's question
would include
this particular lack of correctness.
