CLDR Version 34 Language/Locale Data Released

Version 34 is the latest version of CLDR, the core open-source language data that major software systems use to adapt software to the conventions of over 80 different languages. CLDR data is used by many products for Unicode and language support, including Android, Cloudant, Chrome OS, Db2, iOS, macOS, Windows, and many others.

CLDR 34 included a full Survey Tool data collection phase increasing to 85 languages at the “modern” (full) level, 4 at the lower “moderate” level (suitable for document content), 18 at the basic level, and about 100 others that don’t meet the level requirements.

Among the other changes: new units were added (e.g., atmosphere, petabyte); many new emoji keywords and names were corrected/refined, with updated emoji sort order; and preparations for the New Japanese Era (affecting most software for Japan) were made. The specification was also updated with many changes for Unicode Locale Identifier and BCP 47 Conformance sections, plus defining the syntax of unit identifiers. For other changes, details, and links to documentation, see the CLDR 34 Release Notes.

CLDR Version 26 Released

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.
