    I sometimes wonder whether or not it was a wise choice to regard "LATIN
    SMALL LETTER I" and "LATIN SMALL LETTER DOTLESS I" as distinct. Too late
    to change it now, of course, but (with the benefit of hindsight) it
    occurs to me that if U+0069 had been regarded as dotless, all these
    problems would never have arisen. Western fonts could still have
    rendered it with a dot, Turkish fonts could have rendered it without a
    dot, and everyone would have been happy.

    As an analogy, albeit a rather silly one, if (in mathematics) I put a
    dot over a (single-letter) variable name to indicate (say) first
    derivative or something, I would have to put an /extra/ dot over i,
    would I not? Does that not make it "conceptually" dotless, even though
    it's rendered with a dot?

    Disclaimer: I don't know what I'm talking about. I'm making this up as I
    go along. Don't take any of it seriously.
