Comment (by jyrkive):

 I looked around as to how much effort it would be to implement such
 heuristics. If it was easy enough (e.g. by utilizing an existing function
 somewhere), I could implement it myself and send a pull request.

 It looks like FFmpeg doesn't currently have automatic character set
 detection anywhere. See #4054 for related discussion.

 The mpv media player uses the uchardet library for character set
 detection: https://github.com/mpv-
 player/mpv/blob/c9e7473d67893d9248bedf63530a1e0325a3036a/misc/charset_conv.c#L136

 It seems that implementing this would require pulling in a new library,
 either uchardet or something else. Such a change would be much larger than
 what I'm willing to do.
