@ -370,34 +370,6 @@ Emacs is capable of displaying Emoji and some of the Emoji sequences,
provided that its fontsets are configured with a suitable font. To
make this easier out of the box, the following should be done:
*** Populate composition-function-table with Emoji rules
The Unicode Character Database (UCD) includes several data files that
define the valid Emoji sequences. These files should be imported into
the Emacs tree, and should be converted by some script at Emacs build
time to Lisp code that populates composition-function-table with the
corresponding composition rules.
*** Augment the default fontsets with Emoji-capable fonts
The default fontsets set up by fontest.el should include known free
fonts that provide good support for displaying Emoji sequences. In
addition, the rule that the default face's font is used for symbol and
punctuation characters, disregarding the fontsets, should be modified
to exempt Emoji from this rule (since Emoji characters belong to the
'symbol' script in Emacs), so that use-default-font-for-symbols would
not have to be tweaked to have Emoji display by default with a capable
font. (This has now been implemented, but only one font is currently
considered, please augment the list).
*** Consider changing the default display of Variation Selectors
Emacs by default displays the Variation Selector (VS) codepoints not
composed with base characters as hex codes in a box. The Unicode FAQ
says that if variation sequences cannot be supported, the VS
characters should not be shown, leaving just the base character of the
sequence visible. This could be handled via glyphless-char-display,
by changing the entries for VS codepoints to 'zero-width'. Or we
could display them as a thin 1-pixel space, as we do with format
control characters, by using 'thin-space' there.
*** Special face for displaying text presentation of Emoji
Emoji-capable fonts support Emoji sequences with the U+FE0F VARIATION
SELECTOR-16 (VS16) for emoji-style display, but usually don't support
