Hi,

to get rid of nasty single chars, I use forms like this:

(defun delete-zero-fourteen ()
   "Delete chars ascii octal \\014 "
   (interactive "*")
   (let ((beg (cond ((region-active-p)
		    (region-beginning))
		   (t (point-min))))
	(end (cond ((region-active-p)
		    (region-end))
		   (t (point-max)))))
     (save-excursion
       (goto-char beg)
       (while (re-search-forward (concat (list 12)) end t 1)
	(replace-match "")))))
