;;; Commentary:

;; Sometimes you end up with text that was really UTF-8 but was
;; interpreted as Latin-1, or some other combination.  I found no
;; function to fix that, so I wrote my own.
;;
;; Only tested with the CVS version of GNU Emacs, so YMMV.

;;; Code:

(defun recode-string (string was-really interpreted-as)
  (decode-coding-string 
   (encode-coding-string (string-make-unibyte string) interpreted-as)
   was-really))

(defun recode-region (start end was-really interpreted-as)
  (interactive "r
zText was really in: 
zBut was interpreted as: ")
  (let ((the-text (buffer-substring start end)))
    (delete-region start end)
    (insert (recode-string the-text was-really interpreted-as))))
