See also the Compose key: https://en.wikipedia.org/wiki/Compose_key https://en.wikipedia.org/wiki/Compose_key. I started using a Compose key under Linux five or six years ago. I have progressively accumulated fairly extensive customisation in my ~/.XCompose. (e.g. Compose+;+; = ‘, Compose+"+" = ”, Compose+"+` = ″, Compose+z+Space = ZWSP, Compose+Space+' = NARROW NO-BREAK SPACE, Compose+++1 = THUMBS UP SIGN), Compose+-+-+= = −, Compose+l+* = λ.) Some are of my own division, and some (like Greek letters) are copied from Vim’s digraphs which I had used commonly before setting up a Compose key. I consistently type exactly what I mean. (If I type a straight quote, I meant a straight quote.) My last laptop ended up being a Surface Book; had WinCompose not existed, I wouldn’t have been willing to shift to Windows.
