Hello @hexh250786313 , can you take a look at this? Does the ansi character added by the extension?

[hexh250786313]

@fannheyward Yes. Cause I haven't found another good way to highlight the specific inline code in coc markdown parser.

coc.nvim/src/util/ansiparse.ts

Lines 66 to 81 in 16dfda7

	} else if (foreground) {
	let hlGroup: string
	if (markdown) {
	if (foreground == 'yellow') {
	hlGroup = 'CocMarkdownCode'
	} else if (foreground == 'blue') {
	hlGroup = 'CocMarkdownLink'
	} else if (foreground == 'magenta') {
	hlGroup = 'CocMarkdownHeader'
	} else {
	hlGroup = `CocListFg${upperFirst(foreground)}`
	}
	} else {
	hlGroup = `CocListFg${upperFirst(foreground)}`
	}
	highlights.push({ span, hlGroup })

#5077 may help.
