Form feed characters break odt export

Form feed characters break odt export

[Joseph Turner via General discussions about Org-mode.]

Tested on
GNU Emacs 29.4 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.41, cairo version 1.18.0)
Org mode version 9.7.6 (9.7.6-7a4527 @ /home/joseph/.emacs.d/elpa/org-9.7.6/)

I can export the following Org content to a .odt file, but the exported
file cannot be opened ("Read Error. Format error discovered in the file
in sub-document content.xml at 368,2(row,col).")

--8<---------------cut here---------------start------------->8---
#+TITLE: Foo
* Bar
Baz
\f
--8<---------------cut here---------------end--------------->8---

In this specific context a workaround should be

#+begin_comment
^L
#+end_comment

Or a commented out empty local variables block above.

I have wrote already that I do not like non-printable characters in Org 
files.

I admit that special characters either should cause `org-lint' warnings 
or should be filtered out by exporters.

Specifically to ^L, there was a request to treat it as a page break by 
all exporters (I would prefer some entity or macro instead to not 
deviate from plain text markup).

I have not had a close look at another proposed feature, but I suspect 
that it might make filtering special characters more tricky. (I would be 
happy to hear that I am wrong.)
