@stragu @david let me know if I'm over- or under-explaining, or explaining the wrong thing. ^H "means" backspace (i.e. delete the previous character). More than one means more than one backspace, and it's used in the same way strikethrough might be used to joke about a word you chose not to use. It comes from very old standards for interacting with computers via text. There are several similar codes for things you can't type directly or wouldn't be clear in plain text (e.g. another one is "play a beep on the speaker" which can be shown as ^G). You still might see ^H in a command line program that takes input but doesn't implement it very well. Apologies for the likely double notification. My cat sent hit send before I was done typing this.
