Suggestion: use vim highlight instead of unicode replacement for highlight

[clason]

Depending on the terminal font, the unicode math symbols look very different from the normal text. Would it be possible to use neovim's builtin highlight attributes instead (or in addition)?

From :h ui-event-highlight_set:

["highlight_set", attrs]
	Set the attributes that the next text put on the grid will have.
	`attrs` is a dict with the keys below. Any absent key is reset
	to its default value. Color defaults are set by the `update_fg` etc
	updates. All boolean keys default to false.

	`foreground`:	foreground color.
	`background`:	backround color.
	`special`:	color to use for underline and undercurl, when present.
	`reverse`:	reverse video. Foreground and background colors are
			switched.
	`italic`:	italic text.
	`bold`:		bold text.
	`underline`:	underlined text. The line has `special` color.
	`undercurl`:	undercurled text. The curl has `special` color.

Either bold, italic, or swapping fore- and background will probably look nicer.

I think this is impossible.

The completion is triggered by :help complete() call. The documentation of complete says nothing about highlight.

This plugin is just an experimental hack. For real completion highlight support, we'll need neovim implementing this feature.

Makes sense; I also realized too late that the replacement is done on the python side, not the vim side. Sorry for the noise!
