I’ve used double hyphens for em dashes, because I’ve never bothered to figure out how to do it in Linux. I was a graphic designer for many years, and had a bunch of ASCII Alt codes memorized, but they don’t work in Linux, for whatever reason. I don’t really need them anymore, so I haven’t worried about it. So, I suppose the double hyphens shows I’m human, and definitely not a robot.
