Unicode CLDR Version 48: Submission Open

[image] The Unicode CLDR Survey Tool is open for submission for version 48. CLDR provides key building blocks for software to support the world's languages (dates, times, numbers, sort-order, etc.). All major browsers and all modern mobile phones use CLDR for language support. (See Who uses CLDR?)

Via the online Survey Tool, contributors supply data for their languages — data that is widely used to support much of the world’s software. This data is also a factor in determining which languages are supported on mobile phones and computer operating systems.

Version 48 is focusing on:
  • Unicode 17 additions: new emoji, script names, …
  • Changes to the root and/or English names of many exemplar cities and some metazones
  • Additional number and date formats:
    • New “relative” variant for date-time combining pattern
    • Two new currency formats
    • Rational number formats
    • New ‘Year-First’ calendar formatting for year-month-day order (Gregorian).
  • Units:
    • New units for languages in modern coverage
    • Reworking certain concentration units
  • New Languages available for submission in Survey Tool:
    • Buryat (bua)
    • Coptic (cop)
    • Haitian Creole (ht)
    • Kazakh (Latin) (kk-Latn)
    • Laz (lzz)
    • Luri Bakhtiari (bqi)
    • Nselxcin (Okanagan) (oka)
    • Pāli (pi)
    • Piedmontese (pms)
    • Q’eqchi’ (kek)
    • Samogitian (sgs)
    • Sunuwar (suz)
    • Chinese (Latin) (zh-Latn)
Submission of new data opened recently and is slated to finish on June 11. The new data then enters a vetting phase, where contributors work out which of the supplied data for each field is best. That vetting phase is slated to finish on June 30. A public alpha makes the draft data available in early August, and the final release targets mid-October.

Each new locale starts with a small set of Core Data, such as a list of characters used in the language. Submitters of those locales need to bring the coverage up to Basic level (very basic basic dates, times, numbers, and endonyms) during the next submission cycle.

Once a language reaches Basic coverage, it has the minimum support for use in language selection, such as on mobile devices. In the next submission cycle, the name for that language is also added for translation for all languages at Modern coverage.

If you would like to contribute missing data for your language, see Survey Tool Accounts. For more information on contributing to CLDR, see the CLDR Information Hub.
