[...] * Aren’t language specific sorting rules possible at the current state? Or does "unicode" handle that? E.g. -- DIN 5007-1 (German default sorting) is like zm,zc,uc, but ß should be sorted like ss. -- DIN 5007-2 (German phonebook sorting) would additionally require umlauts to be sorted as ä = ae etc. -- Austrian phonebook sorting sorts umlauts after base vocals, i.e. a, ä, o, ö, u, ü, s, ß. -- Danish and Norwegian: x, y, z, æ, ø, å -- Finnish and Swedish: x, y = ü, z, æ, ä, ö, ø, å (until 2006 v = w) -- etc. (according to https://de.wikipedia.org/wiki/Alphabetische_Sortierung)
sort-lan.lua contains different language definitions. Among others: DIN 5007-1, DIN 5007-2, Duden. Languages "de-AT", "no", "da" and "sv" are ordered as you explain. Swedish doesn’t contain ø (according to https://sv.wikipedia.org/wiki/Ø, it is replaced with ö) or ü (it is a foreign letter to their alphabet). and "fi" seems to order the way you describe. And v is different from w. I would say, Finnish isn’t included in sort-lan.lua.
If nobody objects I’ll add this to the wiki.
Please, it would be extremely helpful (I remember thinking that registers didn’t make any sense in ConTeXt, before someone helped me). Pablo -- http://www.ousia.tk
