    started to be more strict when checking whether converted strings are
    properly formatted. Sudip reports that there are DVDs where the volume
    identification string is actually too long - UDF reports:
    [  632.309320] UDF-fs: incorrect dstring lengths (32/32)
    during mount and fails the mount. This is mostly harmless failure as we
    don't need volume identification (and even less volume set
    identification) for anything. So just truncate the volume identification
    string if it is too long and replace it with 'Invalid' if we just cannot
    convert it for other reasons. This keeps slightly incorrect media still
