The uppercase version of "ß" is "SS". (At least accroding to Unicode and DIN, many Germans however treat "ß" as caseless ...). Unicode allows to types of toUpper/toLower: complete and simplified. The simplified version doesn't change the casing if the number of codepoints would change. Phobos currently excludes all changes where the simplified version would cause a change the length of the UTF-8 encoded string.

For an updated std.uni see http://www.digitalmars.com/pnews/read.php?server=news.digitalmars.com&group=digitalmars.D&artnum=34218

Ok, there was some discussion on this issue, but still I can't get it... Will unicode support, and support for wchar/dchar be in std.sting on 1.0?

It is nice idea to have a roadmap for '1.0' (and at least a 'post 1.0') stuff.
