Byte-strings vs character-strings shouldn't be a problem, as the string=20 itself tells you whether it's multibyte. The problem is bytes vs=20 characters, as both are modeled as small integers. > So perhaps we should have special > functions just for that purpose, and char-equal should signal an error > when presented with unibyte non-ASCII values. Sorry, I don't follow. How could char-equal know whether 224 is a raw=20 byte or the Latin-1 character '=C3=A0'? It'd have to know that, to signa= l an=20 error in the former case.
