Spanish subtitles

[buggaboo]

Hi folks,
I'v egot the latest version BSplayer Pro 1.22, and i'm trying to watch an .ogm movie with 2 audio channels (for english ans spanish) and 2 subtitles (again for english and spanish). The subtitles are included inside the ogm file, they are not in a separated file.
The thing is that when I activate the subtitles in spanish all the 'special' spanish characters, like ?„ ?? ?© ?? and so on are missed, they just don't appear at all, and the final sentence without those characters is rather hard to be read. I've tried to change the subtitle script to 'Central European' and 'Western', but it doesn't work... no other script seems to match either. And i'm sure that the text is OK coz in the Windows Media Player 10 the scripts are displayed properly.
Anybody knows how to solve this problem?
Thanks!!!!!!!
