[画像:stopwatch image ]The beta review period for Unicode 11.0 and related technical standards will close on April 23, 2018. This is the last opportunity for technical comments before version 11.0 is released in Q2 2018. Implementers and interested parties are encouraged to download data files, review proposed updates, and submit comments.

Unicode 11.0 adds seven new scripts, including Hanifi Rohingya, 66 additional emoji characters, including four new components for hair color (for a total of 157 emoj sequences). The set of Georgian Mtavruli capital letters has been added to support modern casing practices.

• For more information about testing the 11.0 beta, see unicode.org/versions/beta-11.0.0.html
• For the current draft summary of Unicode 11.0, see unicode.org/versions/Unicode11.0.0

In addition to the Unicode core specification, five Unicode Standard Annexes and two Unicode Technical Standards have significant specification and/or data file updates that are correlated with the new additions for Unicode 11.0.0. Review of those changes is strongly encouraged during the beta review period.

• New support for Indic virama handling
• Uses Extended_Pictographic property for future-proofing
• A new table of formal regex definitions

UAX #31, Unicode Identifier and Pattern Syntax

• Refines the use of ZWJ in identifiers
• Broadens the definition of hashtag identifiers

UAX #38, Unicode Han Database (Unihan)

UTS #39, Unicode Security Mechanisms

• Updates data to Unicode 11.0
• Enhances discussions of joining controls & combining sequences

UTS #46, Unicode IDNA Compatibility Processing

• Updates data to Unicode 11.0

• Simplifies emoji sequence definitions
• EBNF and Regex expressions for loose matches
• More proposed guidelines: gender-neutral emoji, skin-tone modifiers, ZWJ visible fallbacks, hair-style components
• Mechanism for changing the “facing” direction for emoji

Please review the documentation, adjust your code, test the data files, and report errors and other issues to the Unicode Consortium by April 23, 2018. Feedback instructions are in each public review page. For more information, see the open public review issues.

As technical work gets underway to prepare the publication of Unicode 7.0 (tentatively scheduled for June, 2014), the Unicode Technical Committee has posted proposed updates for several important specifications:

PRI #260, Proposed Update UTS #10, Unicode Collation Algorithm
PRI #261, Proposed Update UAX #15, Unicode Normalization Forms
PRI #262, Proposed Update UAX #44, Unicode Character Database

In UTS #10, collation weights are discussed more generically, with fewer references to the 16-bit weights used in the DUCET. Section 6.3.2, Large Values for Secondary or Tertiary Weights was merged into Section 6.2, Large Weight Values. In UAX #44, the derivation of the Alphabetic property has been updated and the discussion of @missing in Section 4.2.10 @missing Conventions has been simplified to reflect the revised conventions in the UCD data files, which eliminated special edge cases.

Review periods for these new public review issues close January 27, 2014. For details about reviewing and commenting, please see the Public Review Issues page.
