I want to avoid treating non-ASCII chars different from
ASCII. Then, the only solution is to make aset work well
for multibyte characters.

It's not a bug but I agree it's a very bad feature. But for
the case (aset (string ?a) 0 MULTIBYTE-CHAR), I think it's
better to treat "a" as neutral, or in your terminology
"anybyte".
