AFAIK mplayer does not support ucs-2 subtitles, since mplayer only do the 
converting after the subtitle is processed into a subtitle structure. And 
ucs-2 subtitles will not even be recognized because the code assume the 
codepage of subtitle is ascii compatible.

I think -unicode is misleading and does not have anything to do with ucs-2, it 
should be called -two-bytes-code or something similar. The only thing the 
code will do is mergeing two 8-bit char into a single char. It was used in 
the old days with bitmap fonts, where you can generate a group of bitmaps 
with gbk encoding from a font, then load a gbk subtitle with -unicode, so the 
corresponding bitmap will be found according to their gbk code.
