CLDR Version 26 Released

CLDR 26 Coverage Unicode CLDR 26 has been released, providing an update to the key building blocks for software supporting the world's languages. This data is used by a wide spectrum of companies for their software internationalization and localization, adapting software to the conventions of different languages for such common software tasks. This release focused primarily on Unicode 7.0 compatibility, Survey Tool improvements, increased coverage, new units, and improvements to collation and RBNF. Changes include the following:
  • Data Growth: Major increase in the number of translations, with 77 locales now reaching the 100% modern coverage level, and an overall growth of about 20% in data.
  • Units: Added 72 new units, added display names for all units and a new perUnitPattern (eg, liters per second).
  • Collation: Updated collation (sorting) to Unicode 7.0, moved Unihan radical-stroke collation into root to avoid duplication, used import to reduce source size by 23% and ease maintenance. Major changes to Arabic collation.
  • Spell-out numbers: improvements for round-trip fidelity; new syntax for use of plural categories.
  • Specification: documented new structure, \x{h...h} syntax for Unicode code points; construction of “unit per unit” formats; clarified BCP47 and Unicode identifiers, and different kinds of locale lookup, matching, and inheritance.
  • Survey Tool: Major improvements to the UI to make it easier and faster to enter and check data.
Details are provided in, along with a detailed Migration section.

IUC 38 Keynote Presenter Announced


Dr. Mark Davis 絵文字 : ��, ��, and �� = Emoji: Past, Present, and Future
Dr. Mark Davis 
Unicode President and Co-Founder
The Unicode Consortium has announced that its president and co-founder, Dr. Mark Davis, will deliver the keynote address at this year’s Internationalization & Unicode Conference (IUC), November 3-5. Dr. Davis’s talk, Emoji: Past, Present, and Future, will discuss where emoji came from, why they have gotten so popular, where they’ve gone wrong, and what the future will bring.

“Emoji became very popular in Japan right after they were introduced in 1999,” said Dr. Davis. “Once they were added to Unicode in 2010, they became popular worldwide, used in modern mobile phones, texting systems, email, and so on. For example, there were some 6,000 articles on emoji in the month after Unicode 7.0 released, according to Google News.”

Dr. Davis will explore the history of emoji, how they came to be added to Unicode, how they are used in practice, and some of the deficiencies that people see. For example, what about the lack of human diversity and why isn’t there a hot dog emoji? He will then illuminate some of the future additions from Unicode and answer some of the most common questions about emoji.

IUC is the premier event covering the latest in industry standards and best practices for bringing software and Web applications to worldwide markets. Subject areas include the global impact, programming practices, fonts and rendering, and mobile computing. For the eighth year, Adobe will be sponsoring the conference.
