I use vim. It seems like `:set binary enc=latin1` works, though I don't understand why the latin1 part is required.

Here is the bare minimum this is built on, which you can type in yourself if you're paranoid or want to start from the bottom up. Swap in the hexadecimal codepoint of the invisible character after the ?\x (aset glyphless-char-display ?\xfe00 'hex-code)

And as a higher-level configuration you can set most, maybe even all, of the relevant invisible characters (still not sure how 0x34f grapheme joiner fits in) at once with something like: (custom-set-variables '(glyphless-char-display-control '((format-control . hex-code) (variation-selectors . hex-code)))) This will modify values in glyphless-char-display, but it's OK to modify those directly if you need to.
