I don't understand your point here, I'm afraid.
Whenever there's
(multibyte-string-p "/tmp")
=> nil
(multibyte-string-p "bár")
=> t
Why shouldn't I be able to run
(directory-append "/tmp" "bár")
=> "/tmp/bár"
without caring about multibytedness? This is just a string manipulation
function (geared towards file names).
