The Unicode Standard is a character coding system that supports the worldwide interchange, processing, and display of written texts in diverse languages. The Unicode Standard is defined by core specifications, code charts, Unicode Standard Annexes, and the Unicode Character Database.
Unicode 13.0 adds 5,930 characters, for a total of 143,859 characters. It includes four new scripts, for a total of 154 scripts, and 55 new emoji characters.
Periodically, drafts of new versions of the Unicode Standard, including its database and annexes, made available for review and public feedback.
The Unicode Standard is maintained by the Unicode Technical Committee of the Unicode Consortium.
