Subtitels in Slovak/Czech not showing correctly

Greetings to all,

 

I was wondering if anyone could help me solve this. When I download subtitles in Czech or Slovak (slavic languages with characters not found in English), the non-English characters are skipped all together or replaced by different characters, making the subtitles very hard to read. The same subtitles show just fine when player on iMac in e.g. MPlayer or VLC. 

 

Thank you for all your help and suggestions!

You may try adjusting the subtitle encoding.
