> A semicolon is not considered sentence final, whereas a question mark usually is. This makes it easier for software to auto capitalize. So at least that's possible a use case. Such software will need and have a language setting anyway (e.g. for hyphenation). It doesn't have to and cannot rely on code points alone, so the characters (or rather, different uses of the semicolon) needn't have different codepoints.
