Hi Andreas,


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)
                   (t (point-min))))
        (end (cond ((region-active-p)
                   (t (point-max)))))
       (goto-char beg)
       (while (re-search-forward (concat (list 12)) end t 1)
        (replace-match "")))))

Thanks for the code but what I really wanted to know is how Emacs itself
handles this.  I have a feeling that this should not need custom code to
handle.  There is a function 'delete-horizontal-space' and I wanted to
know if and how it applies to this specific 'space' also.

When I encounter a problem not too specific to the special case, I
usually try to find out how other people cope with it before inventing
"yet another wheel(tm)".

If nobody else points me to a already supported way of handling my case
I'll follow Drews advise and pose the question to a wider audience.



some questions remain:

Can't see an  (ascii 160).

Assume you got some character, whose meaning in other context is formatting.

Then it's just a character, who doesn't belong to the mode, you use.

'delete-horizontal-space' is an edit-function, not designed to cure encoding-errors.

Presumable you got chars into a text-mode buffer, which are not text.
That may indicate a bug, but must not.
