[I18n-sig] python implementation of unicode collation algorithm

[James Tauber]

I've made a start on a pure python implementation of the Unicode
Collation Algorithm (UTS #10) but I thought I'd best check with this
SIG whether such a thing already exists.

Not that I'm aware of.

Note that given the sizes of the collation tables, it's probably
better to have them defined in a C module, rather than a Python
data structure.

Yes, this is certainly true of the DUCET, although for language-
specific collation element tables, it would be more manageable.

I'll probably start with a pure Python implementation and then take
it from there (or let someone with better C extension experience
optimize it)

I'm not aware of any pure python implementations.

I've created a pyrex-based C wrapper of the ICU collation library at:

http://svn.zope.org/zope.ucol/trunk/

You don't need pyrex to use this and there is a distutils
setup script to install it.

I'd be happy to make an official release of this if anyone is
interested.

There is also a SWIG-based C++ wrapper of a much larger portion of the
ICU library, including collation at:

http://pyicu.osafoundation.org/

This requires swig, hand editing of makefiles, and dynamic-library
machinations, which is in large part why I ended up writing my own
wrapper.

I'd like to see an official release, even if I do end up doing a pure
Python implementation myself.
