    Has it occurred to anyone yet that the very *concept* of spacing
    diacritics is a hack? Spacing diacritics are used to conduct a sort of
    meta-discussion about characters, as in "A base character o is combined
    with an acute accent ´ to create ó." They are not part of the normal
    writing systems of most natural languages.

    It is as if I were describing the two typical glyphs used for lower-case
    g, the one with "one bowl" and the one with "two bowls," but actually
    showing the separate, constituent pieces of the glyphs instead of using
    words to describe them. They are interesting things to talk about, but
    not necessarily things that need to be encoded in plain text.
