But how do people make these? I searched online and the best I could find were small Japanese communities still using MS Gothic (which is metrically incompatible with Arial/more-used fonts) and halfhearted JPG-to-ASCII-bitmap converters.
Further, how do people manage these? I'd imagine an emoji search, but these millionfold emoticons don't have names; and the other alternatives are "I've got a meme for that scrolls down infinite camera roll" or searching them up every time.
