** Emacs now supports Unicode Standard version 14.0.
+++
** New character script 'emoji' has been created.
Various blocks of codepoints have been split out of the 'symbol'
script into their own 'emoji' script to allow easier specification of
their treatment. Which codepoints are treated as emoji is derived
from the Unicode specifications. Also, Emacs will now use "Noto Color
Emoji" by default for that script. Use:
** Improved support for Emoji
On capable systems, Emacs now correctly displays Emoji and Emoji
sequences by default, provided that a suitable font is available to
Emacs. With a few exceptions, all of the Emoji sequences specified by
Unicode 14.0 are automatically composed and displayed as a single
colorful glyph. This is achieved by changes in the Emacs font
configuration, and by additional character-composition rules for the
Emoji codepoints that follow from the Unicode-defined sequences.
If your system lacks a suitable font, we recommend to install Noto
Color Emoji; Emacs will use it automatically if it's installed. If
you prefer to use another font for Emoji, customize your fontset like
this:
(set-fontset-font t 'emoji
'("My New Emoji Font" . "iso10646-1") nil 'prepend)
to change the font used.
where "My New Emoji Font" should be replaced by the actual name of the
font you want to use.
+++
** Zero Width Joiner (ZWJ) and emoji sequences are now composed.
Emacs can now compose (almost) all the Unicode-14 ZWJ and emoji
sequences (if a suitable font is installed) so that they are displayed
as single glyphs instead of multiple ones. "Noto Color Emoji" is one
such suitable font.
+++
** Composition of emoji has been improved.
If autocomposition is triggered by an emoji character, then the emoji
font is now used to check if composition can be performed, rather than
the font of the first character of the string being composed. This
allows e.g.
'Emoji codepoint' + VS-16
to be displayed using the emoji font even if 'Emoji codepoint' does
not have emoji presentation by default.
The Emoji characters are now assigned to a special script, 'emoji', so
as to make it easier to customize fontsets for Emoji display, as in
the above example. (Previously, the Emoji characters were assigned to
the 'symbol' script, together with other symbol and punctuation
characters.)
+++
** 'glyphless-char-display-control' now applies to Variation Selectors.
VS-1 through VS-16 are now displayed as 'thin-space' by default when
not composed.
not composed with previous characters (typically, as part of Emoji
sequences).
+++
** New command 'execute-extended-command-for-buffer'.
