Emoji set
Twemoji emoji, on any page.
Twitter's open-licensed set. Flat, high-contrast and unmistakable — and, because the licence is permissive, the set a great many sites deliberately load for themselves.
emoji_set: "twemoji"
Ships on X, Discord, WordPress and much of the open web
when to pick it
Pick it for social preview images for X, and any brand that already uses Twemoji on its own site.
why it is not just CSS
A stylesheet cannot draw a glyph the machine does not have.
The only way to render Twemoji emoji is for that font to be installed and chosen — a container decision, not a request one, which is why this is eight browsers rather than eight parameters on one.
