Yes, but ls "Vid\éos" fail.
The point is being able to do something like this:
(shell-command (format "ls %s" (shell-quote-argument (read-string "Fname: "))))
instead of e.g
(shell-command (format "ls '%s'" (read-string "Fname: ")))

Oh yes, i remember now that "é etc.." are not in posix character set,
