The Unicode Standard Acknowledgements

Authorship and Production

The authorship and production of The Unicode Standard is due to the dedication of many people over many years. We are greatly indebted to many individuals for all they have done.

The individuals active on the Unicode Editorial Committee made major contributions that were central to the design, authorship, and review of this version of the Unicode Standard and associated technical publications.

The Unicode Standard Annexes are an integral part of the Unicode Standard. There are also numerous Unicode Standard Standards that are maintained in version synchrony with the Unicode Standard. Acknowledgement of the work of the many contributing authors of those documents, as well as the ongoing work of the maintaining editors and reviewers can be found in the Acknowledgements sections of each of those documents.

Many fonts have been made freely available over the years to print the code charts. See the list of font contributors for detailed acknowledgements.

Other organizations and standards bodies have provided invaluable support. Consortium members and staff were critical to ongoing production , and the Consortium Technical Committees determined the content of the Standard. The Script Encoding Initiative greatly expanded the support of historic and lesser used scripts by the Standard.

Software, Licenses, and Equipment

The following companies have given generously by supplying software and licenses, and facilities and equipment over the years:

  • Adobe Systems Incorporated generously supplied licenses for the Minion typeface family, Adobe® FrameMaker® app and Adobe® Creative Cloud apps, which were used to create the text and graphics of the core specification.
  • Particular thanks for facilities, equipment, and resources are owed to Apple Inc. and Microsoft Corporation. Apple provided much needed hardware in support of the Unicode Han Database. We especially wish to thank Microsoft for its generous support in providing office space, as well as licenses for Visual Studio 2010 and Windows 7.
  • PdfLib GmbH generously provided PDFlib+PDI 6.0.3 for Microsoft Windows and PDFlib TET (Text Extraction Toolkit) 2.1.0 for Microsoft Windows, and Asmus, Inc. provided custom-built software based on these libraries and used for the post-production processing of PDFs for the code charts.
  • Finally, ongoing work on CJK encoding was supported by the generous provision of licenses of Wenlin 4.0 by Thomas Bishop.

Technical Contributors

Hundreds on technical contributors have built the content of the Unicode Standard over the years. We acknowledge their many contributions, focusing here on contributions associated with character encoding, character properties, and the core specification. Technical contributors for the Unicode Standard Annexes and the many other Unicode-associated publications are individually listed in each of those documents. The listings on this page are divided into topical sections: Script and Character Proposals, Emoji and Symbol Proposals, Contributions for Character Properties, and Contributions for Figures. Most of the proposals acknowledged here are permanently archived in the UTC Document Register. Lists of technical contributors for The Unicode Standard, Version 6.0 and earlier can be found in the links for Prior Acknowledgements.

Script and Character Proposals

Over the years many scripts and characters have been added to the Unicode Standard. We express deep appreciation to the following experts who shared their specialized knowledge in order to improve the repertoire of the standard and to allow us to better serve our worldwide user community. Many of these individuals labored long hours to do extensive research and develop detailed proposals for encoding. The Script Encoding Initiative has been particularly important in its efforts to coordinate and shepherd much of this script-related encoding work.

Emoji and Symbol Proposals

Many important new symbols and major symbol sets have been added to the Unicode Standard over the years. In recent times, encoding of emoji has also become a significant portion of these symbol additions. For emoji, in particular, we are indebted to the ongoing and detailed work of the Emoji Subcommittee of the UTC, which processes initial emoji proposals and maintains detailed charts regarding all aspects of emoji encoding. In addition, we are deeply indebted to the following individuals and organizations whose expertise and, in many cases, multi-year efforts have allowed us to greatly extend the symbol coverage of Unicode to better meet the needs of telecommunications, commerce, mathematics and other user communities.

Contributions for Character Properties

The work to develop and verify the consistency of many of the character properties and algorithms is a significant part of the ongoing effort to improve the Unicode Standard. An important role in this effort was played by the International Components for Unicode (ICU) Technical Committee. Many other contributors have made character property proposals, or have otherwise reviewed and commented on character properties.

  • This list is under development.

Contributions for Figures

We are indebted for the continued use of sources for preparation of various figures in the core specification.

  • Grenfel (1921), Austin (1973), and Allen (1931) were used as sources to draw the Figure 6-5, Examples of Ancient Greek Editorial Marks.
  • Parisian Schola Cantorum and Hymns of Faith were the sources used for Arabic musical passages in Figure 21-1.
  • The Kharoshthi map in Figure 14-2 was adapted from Glass (2000).
