And then you encounter some ancient apps without GNU readline support (oracle sqlplus and mysql, I'm looking at both of you). No history support, cursor keys emit characters on the line, literal hell when trying to quickly fix remote database...

I ran into this recently with the default sftp shell on macOS. Tab makes a tab character also. Very annoying.
