Yes, it would be nice if this worked better out-of-the-box for most
people, but I wouldn't want to manually maintain a list of typical char

By the way, ☺ in the terminal here (Debian/bullseye) does take 1
character while 👍 takes two, so perhaps they're also using the same
Unicode data that we're using...
