Composer sorting with accented characters

Java has APIs that sort by locale-dependent Unicode collation but these involve a lot of complex computation and runtime overhead. The sorting algorithm used by MinimServer is hand-written, simple and fast.

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).

Understood. This must have been sorted out before. In fact, I came across this: https://unicode.org/reports/tr10/ Probably too costly to implement in MinimServer, though.

Thinking pragmatically, I agree that one cannot just map accented letters on their non-accented counterparts (e.g., "Schütz" must come before "Schumann"), but for arcane cases like "Š" it would be better than putting it after "Z".
