I'm already using UTF-8 on my server, seemingly without any trouble. The reason I ask the question however, is that I ran across this reference
to an M3U8 format. That hardly looks like any kind of official spec, but could minidlna be modified to read .m3u8 files, and might it not be a bad idea to do some sanity-checking too?
It should already work with UTF-8 characters inside either an m3u or pls playlist. There is nothing extra needed.
