CLDR Version 29 Released

Unicode CLDR 29 provides an update to the key building blocks for software supporting the world's languages. This data is used by all major software systems for their software internationalization and localization, adapting software to the conventions of different languages for such common software tasks. The following summarizes the main improvements in the release.

New BCP47 extension keys have been added for specifying transliteration and emoji presentation, and for customizing locales with region-specific settings. Many new transforms are provided, the rule format has been simplified, and BCP47 IDs have been added for all transforms. Region data now includes appropriate preferences for day periods such as “6:00 in the morning” and “7:00 in the evening”, and there is new structure for choosing appropriate units based on region and usage. A Cantonese locale has been added. The emoji ordering has been improved, and annotations are provided for more emoji and in more locales. The JSON-format data has been extended to include number spellout (RBNF) and script metadata.

The specification and charts have also been updated.
