Unicode Technical Standard #51

UTS#51

Emoji Ecosystem

The Unicode specification that defines how emoji work — including emoji properties, sequences, presentation, and ordering.

UTS#51 (Unicode Emoji) is the technical standard governing all aspects of emoji in Unicode. It defines which characters are emoji, how sequences work, default presentation styles, and the expected behavior for emoji input and display.

Key topics covered by UTS#51:
- Emoji properties and data files
- Emoji sequences (ZWJ, flag, keycap, modifier)
- Presentation styles (text vs. emoji)
- Emoji sorting and ordering
- Guidelines for platform implementations

The standard is updated with each Unicode release to document new mechanisms and emoji.
