Last Call on Unicode 10.0 Beta Review

From: <>
Date: Wed, 26 Apr 2017 11:33:41 -0700

U10 beta imageThe 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 #39, Unicode Security Mechanisms

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

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.
