Last Call on Unicode 10.0 Beta Review

U10 beta image The beta review period for Unicode 10.0 and related technical standards will close on May 1, 2017. This is the last opportunity for technical comments before version 10.0 is released in Q2 2017. Implementers and interested parties are encouraged to download data files, review proposed updates, and submit comments soon.

In addition to the Unicode Standard proper, three other Unicode Technical Standards have significant text and data file updates that are correlated with the new additions for Unicode 10.0.0. Review of that text and data is also encouraged during the beta review period.

UTS #10, Unicode Collation Algorithm Data files
UTS #39, Unicode Security Mechanisms Data files
UTS #46, Unicode IDNA Compatibility Processing Data files

Additional documents are available for public review and will be discussed at the May UTC meeting, such as the final Emoji 5.0 text, and a proposed Unicode character property. For more information, see the open public review issues and the UTC document registry.

The Unicode Standard is the foundation for all modern software and communications around the world, including all modern operating systems, browsers, laptops, and smart phones—plus the Internet and Web (URLs, HTML, XML, CSS, JSON, etc.). The Unicode Standard, its associated standards, and data form the foundation for CLDR and ICU releases. Thus it is important to ensure a smooth transition to each new version of the standard.

Unicode 10.0 includes a number of changes. Some of the Unicode Standard Annexes have modifications for Unicode 10.0, often in coordination with changes to character properties. In particular, there are changes to UAX #14, Unicode Line Breaking Algorithm, UAX #29, Unicode Text Segmentation, and UAX #31, Unicode Identifier and Pattern Syntax. In addition, UAX #50, Unicode Vertical Text Layout, has been newly incorporated as a part of the standard. Four new scripts have been added in Unicode 10.0, including Nüshu. There are also 56 additional emoji characters, a major new extension of CJK ideographs, and 285 hentaigana, important historic variants for Hiragana syllables.

Please review the documentation, adjust your code, test the data files, and report errors and other issues to the Unicode Consortium by May 1, 2017. Feedback instructions are on the beta page.
