For some perspective: The sharp s is made of the long s, which just corresponds to a capital round S in uppercase*; this is why the capital sharp S is not uncontroversial. To this day, “ẞ” is rather exotic and people usually write “SS” or (non-official) “ß”. While I like the capital letter, it may not be Unicode’s responsibility to promote it. (* Though the Ehmcke antiqua does have a capital long S, which resembles an integral sign!)
Daniel Buncic via Unicode <[email protected]>: > Remember, the new > wording that expresses a preference for ẞ over SS (or at least treats > them equally) was only published this year, with the new Duden edition > (which is what people actually read rather than the official rules) > coming out in August, just 3½ months ago. This is how Duden currently explains it: “Bei Verwendung von Großbuchstaben steht traditionellerweise SS für ß. In manchen Schriften gibt es aber auch einen entsprechenden Großbuchstaben; seine Verwendung ist fakultativ ‹§ 25 E3›.” “In Dokumenten kann bei Namen aus Gründen der Eindeutigkeit auch bei Großbuchstaben anstelle von Doppel-s bzw. großem Eszett das kleine ß verwendet werden.” So not exactly prominently featured (“in some fonts”). And again, I find it highly unlikely that the Rat ever intended to make a recommendation here, given that they do not make one regarding “Geografie”/“Geographie” etc.
