In the latest ICU, we took the work we did for Java collation and extended
it substantially (and made it many times faster). It also allows arbitrary
customization at runtime.
I happen to be giving a presentation on it in a few hours at the conference.
For more information, see the draft collation chapter in the User guide, at
http://oss.software.ibm.com/icu/. The presentation (a slightly older draft)
is on my site at www.macchiato.com
