I' am using since a few days Mac OS X Mountain Lion and found that while retaining all my previous Org mode settings and Aquamacs settings, now I am unable to obtain diacritics in Org Mode that is letters such as è à etc.

I only obtain them displayed in Org when they are inside a Org heading

For example: I can write:

* è

and the è is correctly displayed.

But not when I write it in the text.

The symbol of a square appears instead of accented letters.

The coding systems I used with previous Mac OS X (Snow Leopard and Lion) is always the same: that is UTF8

If I try to insert diacritics opening the virtual keyboard from upper menu in Mac OS X nothing change: I always obtain the symbol of a square.

This problem seems to affects only Org Mode because if I use another mode in Aquamacs I have no problems at all in displaying diacritics.

So I am unable to understand what is the cause of this problem.

Has anybody found this? Any idea how to fix it?

Thanks in advance.
