The 1'42" demo on http://screencast.com/t/A9q6CQlLY6 clearly shows that:

- It (now [1]) works from the R terminal

- It works from the Org edit buffer (via C-c '), when sending the commands to
  the iESS process

- It does not work from the Org file itself...

Environment:
- Microsoft Windows 8
- GNU Emacs 24.3.50.1 (i686-pc-mingw32) of 2013-10-19 on LEG570
- Org-mode version 8.2.3c (release_8.2.3c-333-g487c74)
- R 3.0.2

Best regards,
  Seb

[1] I've added the following code in my .emacs to make it work:

    #+begin_src emacs-lisp
    (setq process-coding-system-alist
          '(("R.*" . iso-latin-1)))
    #+end_src
