1512   `format-control': Characters of Unicode General Category `Cf',
1513                     such as U+200C (ZWNJ), U+200E (LRM), but
1514                     excluding characters that have graphic images,
1515                     such as U+00AD (SHY).
1516   `no-font':        characters for which no suitable font is found.
1517                     For character terminals, characters that cannot
1518                     be encoded by `terminal-coding-system'.
1519
1520 METHOD must be one of these symbols:
1521   `zero-width': don't display.
1522   `thin-space': display a thin (1-pixel width) space.  On character
1523                 terminals, display as 1-character space.
1524   `empty-box':  display an empty box.
1525   `acronym':    display an acronym of the character in a box.  The
1526                 acronym is taken from `char-acronym-table', which see.
1527   `hex-code':   display the hexadecimal character code in a box.

1529 Do not set its value directly from Lisp; the value takes effect
1530 only via a custom `:set'
