Aha! I’m rather astounded that this is the case, but happy to know that
we are talking about a use–case that actually affects real users, as
opposed to merely hypothetical ones. Thank you!

You are making unwarranted assumptions about my keyboard :D
But alas, it’s fairly ordinary; I don’t actually have the keyboard of my
dreams. Instead, there are some xkb options that I turn on to make it
more capable. To type a 「"」 I have to press S-', while to type 「“」 I
press Level3-k; it’s a different pair of fingers, but not really any
more difficult or awkward to type.

I use a GUI precisely because the range of characters is so much wider,
making the text work more fun. Also, because the fonts aren’t blurry to
me, ever since I adjusted the font hinting slightly and bumped up the
minimum font sizes significantly (I agree that blurriness is somewhat
subjective).

Yea, that’s why I said that it would need to be statically linked. The
console already uses the framebuffer, it just needs support for reading
TTF fonts (libfreetype) and shaping the text properly (libharfbuzz). I’m
sure some other handwavium would be needed too, but in principle there’s
no reason the Linux console shouldn’t be able to completely support
Unicode text display. It’s just that nobody has done the work.
Of course I hadn’t been thinking of input handling, but xkb does already
exist. While it is a problem that the name starts with an ‘x’, the core
logic of translating keycodes into characters via a keymap is all
there. Presumably with sufficient elbow grease the X protocol stuff
could be filed off and the important bits reused.
I can hear the laughter already, as we propose adding a 2 or 3 megabyte
kernel module. It would be hilarious. Can you imagine it now?
