It would be interesting to make an analysis on how MusicBrainz deals with all these problems, I admit I didn't look much into this. But AFAICT it wouldn't really solve the file system problem, except if you decide to name your files with a hash. Also, you might still want at some point to keep extra information MusicBrainz wouldn't handle, even if you have a MusicBrainz ID stored in the file to identify the music.
About the ASCII, my point was just all about the fact that you can't actually keep only the international name and you need to store the name in different language version. Obviously, I don't have any problem with using UTF-8.
PS: note that UTF-8 won't be able to represent properly mathematical formula... :)
yeah, sorry, was in a rush to go eat. didn't really mean that your worries would all go away, only that musicbrainz might be a good place to look for more info.
