There is none. Sorting is done by the database. That is to say, in the default "comnpatibility" mode, binary "collation" is used - that is, byte-by-byte comparison of UTF-8 encoded data. Which sucks. But we are stuck with it until MySQL gets proper Unicode support.
And until we upgrade to that version. MySQL 4 doesn't have *any* Unicode support -- or any character encoding support, in fact. Every is binary.
But we don't have to wait on MySQL. We would just have to store a Unicode sortkey in cl_sortkey instead of the actual Unicode characters. This would require an implementation of a Unicode sorting algorithm in MediaWiki. It could be language-specific or whatever you want.
