OpenSubtitles forum

Also i have come across greek subs which were useless regardless that setting, text was always displayed as a bunch of weird characters, or just a line of questionmarks. In that case, I just gave up.

See http://msdn.microsoft.com/en-us/library ... 85%29.aspx for list of encodings supported by MS Windows.
Apart from Unicode, Greek can be ISO/IEC 8859-7:2003 and Windows codepage (ANSI) 1253, but also DOS OEM 737, DOS OEM 869, IBM EBCDIC 423, IBM EBCDIC 875, MAC OS Greek, and even Greek national standard ELOT 928...

You can open the sub file with MS word, where you can see the rendering with various proposed encodings at opening, and select a different encoding when saved (except if the file is UTF-8, as this is the only encoding which can be 100% determined by heuristics).

I had the same problem,i solved it by going to Control Panel->Region and Language->Format(TAB) and under format options i choose English (my previous option was greek) . Of course in bs you must choose in options->preferences->Subtitles->font->script:greek.
Hope that i helped you.

Please, use UNICODE. I don't think it's good to impose the use of a particular technology but in this case it is a must.
It's the only rational way to deal with many different languages, sometimes in the same file.

UNICODE is open, well defined and well supported by any decent program. PLEASE, USE IT
