https://bugs.python.org/issue6331
Opened in 2009 with patch and 2 revisions for 2.x.  At least the Python 
code needs to be updated.

Approved in principle by Martin, then unicodedata curator, but no longer 
active.  Neither, very much, are the other 2 listed in the Expert's index.

 From what I could see, both the Python API (there is no doc patch yet) 
and internal implementation need more work.  If I were to get involved, 
I would look at the APIs of PyICU (see Eryk Sun's post) and the 
unicodescript module on PyPI (mention by Pander Musubi, on the issue).
