It’s funny how you describe it as “ASCII with the top bit set”. As in, by default ASCII doesn’t have the top bit set. You can have malformed Unicode too. There are plenty of invalid ranges defined in the UTF-8 spec, does that mean that UTF-8 is just a convention and those malformed pieces are counterexamples to the convention?
