I agree that the details of the glyph vectors are not useful for users. But the character names are hugely useful, even on GUI frames, not only on TTY frames. >> but still no combining character names are displayed on GUI frames. > > I don't think I understand what you mean by that. The names of combining characters under point are now displayed on TTY frames, but still not displayed on GUI frames. This information about buffer characters is needed without relation to fonts and glyphs.
