I generally agree with everything you've written there; however, as a minor nitpick, those skin tone modifiers can be printed in isolation. I'm not sure how this will render on different browsers, but on my terminal:

$ perl -C -E '
    say for
        "\N{U+1F3FB}",
        "\N{U+1F3FC}",
        "\N{U+1F3FD}",
        "\N{U+1F3FE}",
        "\N{U+1F3FF}"
'

And, in a preview, that looks fine on my Firefox v100.0.2 — YMMV.

    You are right, those are printable when used standalone. Which makes them sometimes-printable-characters. Great, another exception that has to be handled when working with text.

    You are in the hallways of the text processing convention. To the sout +h, you see someone selling T-Shirts, to the north is the building exit. The entrance to the lecture hall is to the west. > complain about unicode cavac raises his fist to the gods and shouts "UNICODE!!!". Hr shoots + cavac in the buttocks with a mistletoe arrow.

    perl -e 'use Crypt::Digest::SHA256 qw[sha256_hex]; print substr(sha256_hex("the Answer To Life, The Universe And Everything"), 6, 2), "\n";'
