    This means that a naïve rot13 implementation will not be standard conforming
    w. r. t. <>, clause C6.
    But then, rot13 has never claimed to be so.

    Of course, you could come up with a Unicode-capable, standard conforming
    rot13 implementation -- but what purpose could it ever serve? It would
    not disguise strings written in the n-1 non-Latin scripts, where n > 60.
    So, if something useful is desired, you would have to define a rot-n
    scheme for every Script in Unicode, and put all of those schemes in a
    rot13 successor program. If such a programm would ever be devised,
    it could certainly be made standard conforming (including clause C6).
