The technical information includes:

  • Technical annexes, standards, and reports
  • Data tables and repositories
  • Informational FAQs

Technical Annexes, Standards, and Reports

The Unicode Standard is comprised of the core specification, standard annexes and algorithms, and associated data and behavior specifications. The versions of the Unicode Standard can be accessed at About Versions of the Unicode Standard.

There are three types of technical reports:

  • Unicode Standard Annexes are an integral part of the Unicode Standard
