 Sometimes, especially when ffmpeg is being called programmatically, it is
 difficult or impossible for the caller (or user) to know the character
 encoding of a subtitle file. It'd be useful for libavformat to provide a
 mechanism to detect the encoding if an option is set, using some
 combination of universalchardet, enca, or libguess.
