Ok for Python 2:
$ ./python
Python 2.7.0+ (release27-maint:84618M, Sep 8 2010, 12:43:49)
>>> import sys; sys.maxunicode
65535
>>> x=u'\U0010ffff'; len(x)
2
>>> ord(x)
...
TypeError: ord() expected a character, but string of length 2 found
But Python 3 does use UTF-16 for narrow build:
$ ./python
Python 3.2a3+ (py3k:86396:86399M, Nov 10 2010, 15:24:09)
>>> import sys; sys.maxunicode
65535
>>> c=chr(0x10ffff); len(c)
2
>>> ord(c)
1114111
