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 Technical 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:

• Particular thanks for resources are owed to Adobe Inc., Apple Inc., and Microsoft Corporation. We wish to thank Adobe Inc. for its generous support in providing licenses for Creative Cloud, and Microsoft for its generous support in providing licenses for Windows, Office, and Visual Studio. Adobe Inc. has also provided licenses for Minion 3 and FrameMaker, which were used to produce the core specification through Version 15.0.
• The Unibook charting program provided by Asmus, Inc is the software that is essential to the Unicode code chart production, meeting the challenges created by the ever growing Unicode repertoire, release after release.
• 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.
• For the archival PDF version of the core specification starting with Version 16.0, the CourtBouillon team (Lucie Anglade and Guillaume Ayoub) generously helped us migrate to WeasyPrint, their open source solution for PDF generation.
• Work on CJK encoding was once supported by the generous provision of licenses of Wenlin 4.0 by Thomas Bishop.

Technical Contributors

Hundreds of 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 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 from the world’s writing systems have been added to the Unicode Standard. These have allowed us to better serve our worldwide user community, including diverse language communities and also those preserving historic cultural heritage.

Similarly, many important symbols and major symbol sets have been added over the years, allowing the Unicode Standard to better meet the needs of telecommunications, commerce, mathematics, scrience, and other user communities.

We express deep appreciation to the following experts who shared their specialized knowledge in order to improve the repertoire of the standard and its documentation. 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 Proposals

Since Unicode Version 6.0, encoding of emoji has been a significant part of the Unicode Standard. We are indebted to the ongoing and detailed work of volunteers in the Emoji Standard and Research Working Group who review emoji proposals and maintain detailed charts regarding all aspects of emoji encoding. We also acknowledge the authors of proposals for new emoji that were approved for encoding. See the list of successful emoji proposals for the names of proposal authors.

Contributions for Character Data

The work to develop and verify the consistency of many of the character properties 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.

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).
