Sorry I didnt' mention that I use the latest version of everything: so Org 7.8.11 and Aquamacs version 2.4. based on GNU Emacs 23.3.50.1.

Bastien thanks for the suggestion.
I have tried what you suggested and used Emacs from the Terminal Application in Mac OS X: in this case I have no problems. Diacritics inserted in the org file by hitting the proper key in the Italian keyboard layout are correctly displayed:

File Edit Options Buffers Tools Help                                            

diacritics è

à ì

diacritics are displayed


-uuu:---F1  myfile.org     All L1     (Fundamental)-----------------------------

What should I do to check which version of Emacs is charged when I use the Terminal application?

Do you have this error with

emacs -Q
C-x f ~/myfile.org
[some diacritics]

?

If you use another version of Org on top of the Emacs version,
maybe you can also check emacs -Q + loading this version and see
what does not works.
