According to wikipedia "ß".upcase is "SS", except in the case of legal documents it remains "ß". I checked irb and "ß".upcase is "ß", so I guess strings in ruby are of type "german legal document." I also just learned that the reason there's no uppercase ß is that no words start with ß, so titlecase would never touch it.
