What's new in this cycle

  • If you are new to CLDR contribution, please read the prerequisites above first.

  • If you have contributed to CLDR in the past, below is the information that's new or changed since the last release.

Progress Widget

There is a new style for the progress widget that shows your voting progress on the page in the upper right corner of the Survey Tool next to the Info Panel toggle. You will see details of your progress when you hover over the widget, including what progress is being measured, and the total number of items remaining for you to vote on in that category. Your progress is measured based on the coverage level you have set, so make sure that it is set correctly.

Note: The total progress widget is currently only visible when the dashboard is open.

Page progress

Progress bar shows progress of items on page for your coverage level.

Overall progress

Progress bar shows progress of items overall for your coverage level.

Update to forum post responses

In order to reduce confusion there are no longer buttons to 'Agree' or 'Disagree' with a forum post (earlier people mistakenly thought that clicking the agree button would also change their vote).

If you change your vote an automatic posting indicating agreement will be added to the forum as before.


The examples have been augmented, especially for Minimal pairs. An example with an ❌ shows a case where the pattern has an inappropriate placeholder substituted. That example should be ungrammatical; if it is grammatical, then either the translated unit or the minimal pair pattern itself is incorrect. The example will show in the Info Panel, and also if you hover over the item.

Survey Tool

Translation quality

The following are areas where we have seen data quality issues or those that need your attention more carefully.

  • Avoiding voting for English

    • For items that do not work in your language, please don't simply use English. Find a solution that works for your language. For example, if your language doesn't have a concept of "quarters", use a translation that describes the concept "three-month period" rather than “quarter-of-a-year”.

  • Dealing with “Same as code” errors:

    • Since v37, if you voted for the Code, a Same as Code error will raise.

    • When translating codes for items such as languages, regions, scripts, and keys, it is normally an error to select the code itself as the translated name (such as “en” as the translated name for code “en” English), except for some specific cases including certain script codes (for example, code “Thai” is also the name for script Thai in several languages).

    • If the error appears under Typography, you can ignore. [CLDR-13552]

  • Bidi example limitations [CLDR-10674]. If you are working with a bi-directional languages, be aware of the Right-to-Left and Neutral context. Survey Tool only shows examples with a strong RL context, and we have been issues where vetters removed the ALM bidi marks or modify the patterns without considering the neutral context. Please be cautious of changing the bi-di formatting data.

  • Handling Display name menu variants

Known Issues

Last updated: 2022-05-24

Please review this list before getting started to avoid creating duplicate tickets. This list will be updated as fixes are made available in Survey Tool Production. If you hit a problem, please file a ticket.

  1. CLDR-15662 LocaleCompletion (third) Meter percent too high

  2. Expanded section in left navigation panel flickers if clicked [CLDR-14750]

  3. Same name collision error. If two items differ only by upper/lower case or punctuation, it still counts as a collision. However, currently, only one of them is flagged as an error. [CLDR-11274]

  4. Images for the plain symbols. Non-emoji such as , √, », ¹, §, ... do not have images in the info pane. [CLDR-13477]

    • Workaround: Look at the Code column; unlike the new emoji, your browser should display them there.

  1. Careful with square brackets. Brackets "[ ]" under Alphabetic information are used to group the alphabetic information and they are not part of the data. [CLDR-13180]

    • Workaround: Please ignore the [ and ] characters in the Alphabetic information and do not try to update the data to exclude the [ and ].

Resolved Issues

Last updated: 2022-05-09

The following list of previously listed on the Known Issues have now been resolved and fixed:

  3. Issues importing your votes. Error message: "Status 500 Internal Server Error; URL:..." [CLDR-15178]

  4. Unclear to vetters why they can't edit locales that are not open or only open for specific paths [CLDR-15224]
