[MPlayer-dev-eng] Windows1250 to ISO8859-2 subtitles conversion patch

[berdzi]

Hello

I've recently wrote a small patch to Mplayer that could be pretty useful
for Poles. Its purpose is to convert at playing time subtitles coded is
Windows 1250 format to ISO-8859-2. Most Polish subtitles are coded in
Windows 1250 and I always had to convert them with external software to
ISO. I include version for today CVS (20020325).

I tested it and I hope it will be useful

Regards, Berdzi.
