In typography it seems to be the standard that italics functions as a toggle switch; if there's text within a longer italicised passage that should itself be italicised, it's unitalicised.
Just who are these Five Guys, and why haven't I heard of them before, she thought to herself.
This has always seemed suboptimal to me. It takes me a moment to parse that the suddenly un-emphasised text is meant to be on a second layer of emphasised, and it can make it confusing to tell where an icalicised passage ends if it's got some second-layer-italics right at the end of it. I'm here to propose the obvious solution:
Early computers could not render italics directly but simulated them by moving the letters horizontally during the horizontal blanking period
