It's a contraction of s and z into one letter, called "esszett" in german and typically used in the german language. It's used in places where a sharp 's' occurs, although it's use has been reduced since the orthographic "reform" of the '90s. I believe the letter originated as a ligature itself, although it's beyond me why Calibre would replace a ligature of 'fl' by one of 'sz'.
