- PhilipRoman 2y agoApparently this used to be a common thing, groff has a feature to output bold text for TTY devices by backspacing and re-printing each character twice. You can get underlined text in a similar way using backpace and underscore. It doesn't work out of the box on terminal emulators, but less(1) does this rendering for man pages, etc.
- sevensor 2y agoThat's how we did it with typewriters, back in the day. You could backspace and overstrike with another character, to make a composite symbol.
