dup of #3211

By adding U+FE0F (as noted above, and in #3211) I can change the highlight color, but the emoji is single-width. Is there a way to have both double-width display and highlighting?

Ah I think I got your problem. Color emoji are not colored by text attributes. They are rendered in whatever color comes from the font. If you want to color them, then you follow them by \ufe0e and they will be rendered as text, single-celled and colored by the current foreground color.

This is the way they are supposed to be rendered. If vscodium is doing it differently, then that is a bug in that program.

Got it. Thanks for the info!
