I realised that I don't only have vertico, I also use marginalia, which is
responsible for the faces. Disabling marginalia (but keeping vertico) gives a
much more spartan look, but the issue remains:

Moving the highlight still changes the characters to the box with hex
codepoints, and taking a screen shot changes all of them (with no way of getting
back the characters).

Vertico doesn't apply any special faces to the candidates, it just uses the
'highlight' face for the current selection, which only specifies a background
colour.

I'm not sure how to do that.

Right, sorry for the confusion.

No, sorry, what I meant was that I can copy & paste the characters into them and
they display fine.

I mentioned Vertico because that's actually the only time the characters are
displayed. Anywhere else, e.g., if I insert them into a buffer, they
always appear as hex boxes.
