[OS X Emacs] Aquamacs ESS and special characters

[Petar Milin]

Hello all!
I am very new in Mac OS world (coming from long Linux experience, from Ubuntu and Debian, to Fedora). After some search for the best editor I decided to go for Aquamacs, which fits nicely to my needs (Python, LaTeX, R, and very little C). ESS is great, but I cannot make it print special characters (Croatian, Serbian etc.). I have found one post explaining similar problem:
http://emacs.1067599.n5.nabble.com/unicode-character-in-aquamacs-td237707.html
However, there is no solution. It seems that the guy lost his patience and went for some other editor.

Can anyone help me? Please, I would appreciate a lot. I would like to stick with Aquamacs, which works so greatly.

How can I get unicode, or cp1250? Or special character, in principle? Currently, I get only dots at the place where our weird characters should appear… :-(

All the best,
PM
