Here is another recipe, maybe more to the point:
-------------------->8-------------------------------------
;; -*- coding: binary -*-
(let ((d "/tmp/\303\204")) ;; utf-8 for german umlaut "A
(when (file-exists-p d)
(delete-directory d t))
(make-directory d)
(append
(list (car (directory-files d t))
(file-exists-p (car (directory-files d t))))
;; switch to a multibyte buffer
(with-temp-buffer
(list (car (directory-files d t))
(file-exists-p (car (directory-files d t)))))))
--------------------8<-------------------------------------
If I save this somewhere (/tmp/foo.el), do
$ LC_ALL=C emacs -Q /tmp/foo.el
and evaluate it with C-x C-e, the minibuffer displays
=> ("/tmp/\301\203\300\204/." nil "/tmp/\303\204/." t)
.
I hope that clarifies it.
