You could always dig up an ASR-33 and use ed or vi. <grin> I realize that’s close to heresy in this forum, but once glass teletypes became a thing, variable width characters weren’t far behind.
IIRC: I tried Fira and other ligature supporting fonts a few years back, and decided that I’d spent TOO many years in the 80 column world where everything was always lined up, and I couldn’t handle the “improvements”.
