This is absolutely the case. From the perspective of grapheme- characters, and ignoring ligatures as a pure typesetting issue, Eszett is the ONLY character in all of unicode that upcases into a different number of characters. I'm using an ugly kluge to put off changing the length of any string until a canonicalization operation, or return the upcase as a single non-standard character (yet another character which doesn't exist in unicode), but I'm sorely tempted to simply declare all use of eszett, given its unique status in the history of human writing, to be an error.
