    What would be an example of the difference?

    What kind of havoc? If the OS is to normalize file names, I consider
    NFC preferable, because it guarantees that a user-requested file name
    of an allowed length will still be of an allowed length after

    The Unix way would be to have the normalization mode (NFC, NFD,
    HFS+NFD, none) a file system attribute specified during file system
    creation (or mounting, if the FS format does not support that flag).
