From Die Zeit, I learn that new orthographic rules issued by the Rat für deutsche Rechtschreibung specify that ß / esszett / sharp s shall now have an uppercase form.
From the comments there, I learn further that codepoint U+1E9E has already been assigned to this character.
Will the default collation used for upper-case be changed to map U+00DF to U+1E9E?
I notice that lower-case already maps U+1E9E to U+00DF, in the version 7.9 on my disk. (Am I already that far out of date? Sigh.)
best regards,
