1414 Each element has the form (GROUP . METHOD), where GROUP is a
1415 symbol specifying the character group, and METHOD is a symbol
1416 specifying the method of displaying characters belonging to that
1417 group.
1418
1419 GROUP must be one of these symbols:
1420   `c0-control':     U+0000..U+001F, but excluding newline and TAB.
1421   `c1-control':     U+0080..U+009F.
1422   `format-control': Characters of Unicode General Category `Cf',
1423                     such as U+200C (ZWNJ), U+200E (LRM), but
1424                     excluding characters that have graphic images,
1425                     such as U+00AD (SHY).
1426   `no-font':        characters for which no suitable font is found.
1427                     For character terminals, characters that cannot
1428                     be encoded by `terminal-coding-system'.
1429
1430 METHOD must be one of these symbols:
1431   `zero-width': don't display.
1432   `thin-space': display a thin (1-pixel width) space.  On character
1433                 terminals, display as 1-character space.
1434   `empty-box':  display an empty box.
1435   `acronym':    display an acronym of the character in a box.  The
1436                 acronym is taken from `char-acronym-table', which see.
1437   `hex-code':   display the hexadecimal character code in a box.
1438
1439 Do not set its value directly from Lisp; the value takes effect
1440 only via a custom `:set'
1441 function (`update-glyphless-char-display'), which updates
1442 `glyphless-char-display'."
