Problem with Non English(Farsi, ...) subtitle

When I want to see a movie or video in mac os x (with VLC, DivX Player, Quick Time) and want to load subtitles, these video player applications can't load my subtitle correctly show in strange text.

My subtitle language is Farsi (RTL language). I must change some Unicode settings, but I don't know where anyone has any idea?

According to Trezoid answer on superuser the solution is:

By default the language encoding on VLC (and possibly others) is set to "default" which is windows-1252 (possibly only if your language is set to english, but I'm not sure)

This will not display other languages very well. To fix it, open up VLC preferences, click on the Subtitles and OSD tab, and change "default encoding" to UTF-8

This will give the program a much wider choice of characters to display from allowing it to render the characters as they should be.

I had the same problem and fixed it in this way: open VLC, preferences, subtitle/OSD, and change default coding to one of Arabic languages.
