But it doesn't use create-glyph, it sets up display-table so that some characters are displayed as strings of other characters. That is a different feature. It has nothing to do with create-glyph. > As a separate feature, you can use display-table to display a > character code as a series of glyphs. But each of those glyphs > is supposed to occupy one space on the screen. It works as expected even if they occupy more than one screen space. I think that is a misunderstanding. The sequence of glyphs will naturally use up more than one screen space, but on a tty each glyph is supposed to use just one, right? But that detail is not crucial. So I think create-glyph is not important for internal.el. Correct.
