Actually, that is in the Unicode database (SpecialCasing.txt): 00DF; 00DF; 0053 0073; 0053 0053; # LATIN SMALL LETTER SHARP S > However, the point I wanted to make was that these mappings don't depend > on the locale setting of the C lib - you have to explicitly > access the mapping in the context of a locale and/or text. I don't get that point. SpecialCasing.txt is clearly intended to take locale context into account. Whether this is the "C locale", or some other locale mechanism, is out of scope of the Unicode specification. It could be the C locale (and indeed, the C locale implementations often take the Unicode casing procedure into account these days).
