Unicode CLDR 22.0 contains data for 215 languages and 227 territories—654 locales in all. The main focus for this release is to flesh out data items in major languages and locales: yielding an increase of over 100% in the total number of data fields. Other major features include the addition of keyboard mapping data for different platforms, the new Zhuyin (Bopomofo) sort order for Chinese, and script metadata. There are also enhancements to compact decimals (such as formatting 1,000,000 as “1 million” or “1M”) for different languages and to rule-based number formats (such as writing 423 as "four hundred and twenty-three").

The table above points to the files for this release. For a description of their purpose and format, see the Key.


The main features include the following (see the Delta link above for a full list of changes, aside from data additions and corrections):

Data changes

  • Very significant increase in data
    • Over 197,600 language-based data entries (new, revised, or confirmed) through the Survey Tool. Top languages were French (9,688), Chinese (8,379), Indonesian (6,561) and Thai (6,471); with 89 others.
    • Many missing translations added to locales: Japanese, Arabic, Indonesian, Hebrew, Thai, Lao, Khmer, Dzongkha, Ewe, Nepali, Slovak, Amharic, Vietnamese, Sinhala, Estonian, Latvian, Catalan, Macedonian, and many others.
    • New language locales: Bosnian (Cyrillic), Kashmiri, Asturian, Tachelhit (Latin), Ossetic, Ngomba, Meta', Ngiemboon, Volapük, Kako.
    • Over 300,000 data items added in this release; an increase of over 100% in the total number of data fields. This does not count inherited items, which would result in a much larger figure.
  • New or improved collation (sorting order): new Zhuyin (Bopomofo) collation for Chinese, the preferred collation order for many users of traditional Chinese; updated Thai collation.
  • Over 370 new files of keyboard mappings, collected from publicly available data for four different platforms: Android, Chrome OS, OS X, and Windows.
  • Script metadata property values for all 107 scripts in Unicode: web-rank, sample characters, bidi-order, casing, spaces-used, etc.
  • For compact decimals (powers-of-ten notation), the addition of long forms (“1 million” vs “1M”) and plurals (“1 million” vs “2 millions”, used by many languages).
  • Significant vetting of rule-based number format data (such as writing 423 as "four hundred and twenty-three") to correct spellings and add missing data for common word inflections and some numeric values.
  • Many new region locales for existing languages, including new en_150 locale for European English.

Structural additions

  • Structure for keyboard mappings, providing a format for interoperable interchange of keyboard data.
  • New short width for weekday names (e.g. Mo, Tu, We), useful for date/time formats with limited display space.
  • For compact decimals (powers-of-ten notation), the addition of long forms and plural categories.
  • Script metadata properties
