    I know that. But I did not discuss about NFC/NFD. Only about NFKC/NFKD that
    was not designed for interoperable interchange purpose.

    The fact that IDN makes some use of it (now in a non-conforming way because
    it uses its own rules to define its own sets of mappings, and to preserve
    compatibility with future evolutions, it does not automatically integrate
    all Unicode additions) is another problem, but anyway IDN is not a Unicode
    specification and its correct implementation is not mandatory for Unicode

    I see the nameprep process as just a use of Unicode, that already assumes
    the fact to be considered a non conforming process (given that it rejects
    now some canonical equivalences andconsiders instead some characters as
