I'm not sure, because I don't know what that would be like in practice. If I could see it actually handle some characters, I would probably see how to answer. > แบต is not supported by latin1-display, as it is not an ISO 8859 > character. You need to turn on a more thorough feature. Try this: > M-x latin1-display-ucs-per-lynx RET I just gave that command, but it doesn't do anything for the แบต character. > I could show you how to install such a > composition rule, but I don't think it will do anything on your > console, since it doesn't support ligatures. I don't WANT autocomposition on my Linux terminal. I'm talking about how to display a ligature character that actually appears in the buffer. If latin1-display is the way, it ought to handle ligature characters too. -- Dr Richard Stallman (https://stallman.org) Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
