Composer sorting with accented characters

It would be possible to extend this hand-written algorithm to cover the first 512 or 768 Unicode codepoints rather than the first 256. The main issue with this is understanding the correct collation order for characters such as Ȑ Ș Ȥ (perhaps fairly intuitive) and Ƞ Ȝ Ƿ Ƕ (much less intuitive, at least to me).

Apologies if I'm massively over-simplifying here; I understand that you wouldn't want to use the Java API's you refer to at runtime, but couldn't they be used to sort the 768 codepoints you're talking about, so that they can be plumbed into your custom algorithm?
