 This ticket is essentially a variant of #7203. #7203 was closed because
 the file in that ticket uses ID3v2 tags and the tag in question was
 encoded as Windows-1251 but tagged as ISO-8859-1.

 However, as far as I can tell, ID3v1 has no way to specify the character
 encoding. FFmpeg simply assumes UTF-8, and it's not always right. The
 attached file has the "artist" field encoded as Shift-JIS. Its value is す
 ずき けいこ.

 It would be great if FFmpeg attempted to heuristically detect character
 encoding of ID3v1 tags.
