The following is a minimal example which does not work under Python
3.1.1 but functions as expected on Pyhton 2.6 and 3.0.

Python 3.1.1 believes the single UTF-8 glyph is two entirely different
(and illegal) unicode characters:

Traceback (most recent call last):
  File "t.py", line 2, in <module>
    print('𐑛')
UnicodeEncodeError: 'utf-8' codec can't encode character '\ud801' in
position 0: surrogates not allowed

Test system is Ubuntu 9.10-beta 32-bit
