Not sure why this discussion is on the Unicode list instead of the cldr-users list... Anyhow...
While I do find (in CLDR's collation de.xml) a <collation type="phonebook"> I don't find any variant doing the Austrian phonebook variant you mention. Maybe you could file a ticket for adding that to CLDR. (Using that same tailoring for Volapük is a separate matter.) /Kent K Den 2012-01-01 18:46, skrev "Otto Stolz" <otto.st...@uni-konstanz.de>: > In Austria, a third scheme is used in telefone directories > (but not in the yellow pages): Here, Ä, Ö, and Ü, are > indeed treated as distinct letters, to go between A and B, > O and P, and U and V, respectively; and ß is treated as a > distinct pair of letters, ro go between SS and ST.
