It would be nice to get the same behaviour in Python 2.x and 3.x to help 
migration from Python2 to Python3 ;-)

unichr() (in Python 2.x) documentation is correct. But I would approciate to 
support surrogates using unichr() which means also changing ord() behaviour.

Why? Using surrogates, you can use 16-bits Py_UNICODE to store non-BMP 
characters (code > 0xffff).


I can open a new issue if you agree that we can change unichr() / ord() 
behaviour on narrow build. We may ask on the mailing list?
