[Orgmode] Exporting non utf8 org documents

[Francesco Pizzolante]

Hi,

I have colleagues who are writing Org documents with latin-1 encoding and when
I export these documents to LaTeX I run into problems, because Org assumes
utf8.

Here's a little example:

--8<---------------cut here---------------start------------->8---
#+LATEX_CLASS: article

* Ceci est un test

  Voici un petit texte rédigé en français.

* COMMENT Setup

# This is for the sake of Emacs.
# Local Variables:
# coding: iso-latin-1
# End:
--8<---------------cut here---------------end--------------->8---

The exportation to LaTeX gives the following result:

--8<---------------cut here---------------start------------->8---

\end{document}
--8<---------------cut here---------------end--------------->8---

When compiling, due to the \usepackage[utf8]{inputenc} directive, I get this
error:

ERROR: Package utf8x Error: MalformedUTF-8sequence.


In order to fix this issue, I see the following solutions:

- Would it be possible for Org to automatically get the coding system of the
  buffer and then generate the correct option for the inputenc package?

or

- Would it be possible to have a variable like #+CODING-SYSTEM: iso-latin-1
  which would be used to generate the correct option for the inputenc package?

Any other proposition or idea is welcome.

In addition, Org should use the `utf8x' option (instead of `utf8') which
enables to handle unbreakable spaces (useful in french).

Thanks.

Regards,
Francesco
