The new smiley-style called emoji takes advantage of the harfbuzz glyph
rendering to represent smileys as colorful unicode emoji rather than
images.

* lisp/gnus/smiley.el (smiley-style): Add emoji
tag. (smiley-emoji-regexp-alist): New defcustom. (smiley-update-cache,
smiley-region): Support emoji (non-image) replacement.
---

How about an option to use emoji for smileys in Gnus?
