1523 Each element has the form (GROUP . METHOD), where GROUP is a
1524 symbol specifying the character group, and METHOD is a symbol
1525 specifying the method of displaying characters belonging to that
1526 group.
1527
1528 GROUP must be one of these symbols:
1529   `c0-control':     U+0000..U+001F, but excluding newline and TAB.
1530   `c1-control':     U+0080..U+009F.
1531   `format-control': Characters of Unicode General Category `Cf',
1532                     such as U+200C (ZWNJ), U+200E (LRM), but
1533                     excluding characters that have graphic images,
1534                     such as U+00AD (SHY).
1535   `no-font':        characters for which no suitable font is found.
1536                     For character terminals, characters that cannot
1537                     be encoded by `terminal-coding-system'.
1538
1539 METHOD must be one of these symbols:
1540   `zero-width': don't display.
1541   `thin-space': display a thin (1-pixel width) space.  On character
1542                 terminals, display as 1-character space.
1543   `empty-box':  display an empty box.
1544   `acronym':    display an acronym of the character in a box.  The
1545                 acronym is taken from `char-acronym-table', which see.
1546   `hex-code':   display the hexadecimal character code in a box.
1547
1548 Do not set its value directly from Lisp; the value takes effect
1549 only via a custom `:set'
1550 function (`update-glyphless-char-display'), which updates
1551 `glyphless-char-display'."
