Playlist file used by various audio and video playback programs; uses the same formatting as an .M3U file, except the text stored in the file uses UTF-8 character encoding; often used for storing playlists that have song names in different languages.
NOTE: Some M3U files may already use UTF-8 character encoding. However, M3U files may also use other character encoding standards. Therefore, the M3U8 extension is used to explicitly state that UTF-8 character encoding is used.
