   On graphical displays, some characters may have no glyphs in any of
 the fonts available to Emacs.  These @dfn{glyphless characters} are
 normally displayed as boxes containing the hexadecimal character code.
 Similarly, on text terminals, characters that cannot be displayed
 using the terminal encoding (@pxref{Terminal Coding}) are normally
 displayed as question signs.  You can control the display method by
