    This will not happen.
    Linguists will continue to use their PUA code points (or even their
    8-bit fonts), which employ these characters perfectly (albeit using
    precomposed glyphs for the used combinations).

    It *is*, at least for the applications in dialectology where groups of
    three characters linked by one of the proposed triple diacritics have a
    well-defined and documented meaning.

    This is also proven by the fact that the existing PUA characters
    fulfill perfectly the needs of the relevant academic communities,
    except being interchangeable without using special fonts containing
    these PUA characters (a request which could be overcome when these
    characters are contained in Unicode).

    Problems are there to be solved, and they are solvable.
    E.g., simply state that no line break may occur in the realm of a
    diacritic spanning over three letters.

    Latin *is* a complex script, anyway.
