At that time what he wanted is that Emacs would=20 automatically replace such ligatures by two letters in his Linux console,= =20 and that's what he got: Eli improved the latin1-display-ucs-per-lynx=20 function in fd42ba3adb. At that time diamonds were considered=20 "unhelpful", and he said for example: "I doubt any user wants to see a=20 diamond instead of `fi'." During that discussion, the bug that is now objected against was also=20 fixed, by 10c680551e. I, too, doubt any user wants to see a diamond instead of an actual=20 character! Why are these diamonds suddenly useful again? How comes that= =20 a proposed solution with which ligatures such as "=EF=AC=81" are actually= =20 displayed as "=EF=AC=81", with which UTF-8 is actually supported instead of= =20 having to resort to ugly hacks such as latin1-display-ucs-per-lynx, and=20 with which missing glyphs are in fact again displayed with these same=20 diamonds, is criticized?
