OK.

I had not seen this reply yet, when re-sending my question yesterday night.
I've got the solution from Chris to test...

I don't understand the details of the export process. For me, if I have such a
table:

| Item     |  % |
|----------+----|
| Sample 1 | 20 |

and I want it framed, adding `#+LaTeX: \begin{framed}' and `#+LaTeX:
\end{framed}' should be transparent for the Org -> LaTeX conversion process.

It is not: as soon as I do such a thing, I need to escape the `%' sign:

| Item     | \% |
|----------+----|
| Sample 1 | 20 |

For me, the `%' should be escaped independently of whether I add or not such a
LaTeX tag.

OK.

Thanks that *you* fixed it ;-)

I guess you talk to someone else? ;-)

Here is one non-breaking space: `Â ', and here is what Emacs tells me about it
(when `C-u C-x ='):

--8<---------------cut here---------------start------------->8---
        character: Â  (160, #o240, #xa0)
preferred charset: unicode (Unicode (ISO10646))
       code point: 0xA0
           syntax: .    which means: punctuation
         category: .:Base, b:Arabic, j:Japanese, l:Latin
      buffer code: #xC2 #xA0
        file code: #xC2 #xA0 (encoded by coding system utf-8-emacs-unix)
          display: by display table entry [?øŽ€‚·] (see below)

The display table entry is displayed by these fonts (glyph codes):
øŽ€‚·: -- no font --
 face: `bold'

Character code properties: customize what to show
  name: NO-BREAK SPACE
  old-name: NON-BREAKING SPACE
  general-category: Zs (Separator, Space)
  decomposition: (noBreak 32) (noBreak ' ')

There are text properties here:
  fontified            t
--8<---------------cut here---------------end--------------->8---

I insert them when I have a colon (for example) preceded by a space: that
space is automagically converted to non-breaking one, thanks to the following
code in my `.emacs' file:


--8<---------------cut here---------------start------------->8---
(defun my-insert-colon ()
  (interactive)
  (if (eq (char-before) ?\ ) ; normal space
      (progn
        (backward-delete-char 1)
        (if (equal mode-name "PDFLaTeX")
            (insert "~:") ; for LaTeX-only
          (insert "Â :"))) ; non-breaking space
    (insert ":")))

(defun my-double-keys ()
  "Specific keys."
  (interactive)
  (local-set-key ":" 'my-insert-colon))

(add-hook 'text-mode-hook 'my-double-keys)
(add-hook 'message-mode-hook 'my-double-keys)
--8<---------------cut here---------------end--------------->8---

If you don't mind, this is on my wishlist of Org-mode features... You see my
Emacs code handles it when I write LaTeX myself, something I wanna avoid like
pest now that I'm more than delighted with the powerful possibilities and nice
reading presentation environment of Org.

Best regards... and thank you very much once again!
