That would be great.

I guess in a unibyte session, it makes sense, because in such a case,
unibyte buffers do contain characters and the user explicitly tells us
"don't bother me about multiple charsets, just pretend all fits within
8bits".

Is such a buffer necessarily unibyte ? Why not multibyte ?
Or is it for performance reasons ?
And what should happen if we paste text containing 8859-5 ou BIG5
text in such a buffer ?

Agreed. But we should encourage people to "do it right" by calling
the appropriate encoding/decoding functions so it works for all cases.
I believe that a good way to encourage people is by discouraging the use of
string-make-unibyte (and other ways to use copy_text similarly).
