Current Errata Notices

Date  Summary 
2019-05-15 The code chart for the Adlam script published in the Unicode Standard for Versions 9.0 through 12.0 used a preliminary font with a sub-optimal design for the script. This font for the Adlam script will be replaced in a future version of the standard with the Ebrima font, which uses an improved design that now has widespread acceptance in the Adlam user community. The original font is shown in the left partial chart below; the Ebrima font is shown on the right side below. Click on each graphic to see a full chart and names list display for each, respective font. The current code chart for Adlam will be updated as soon as feasible, without waiting until next year's publication of Unicode 13.0.

2019-03-08 The character count totals in Table D-5 in the Unicode 12.0 core specification (p. 954) are off by one for Unicode 11.0 and Unicode 12.0.
For the "Alphabetics, Symbols" row, the correct count is 37,159 (not 37,160) for Unicode 11.0 and 37,704 (not 37,705) for Unicode 12.0. This off by one value cascades down through the subtotals in those columns of the table.
The correct totals for the traditional Unicode character count should be 137,374 for Unicode 11.0 and 137,928 for Unicode 12.0.
These errors in Table D-5 will be corrected in the next update of the core specification.

Reports of errors in published documents, such as the Unicode Standard itself or Unicode Technical Reports, may be filed using the Unicode Consortium's contact form. If confirmed, and depending on the nature of the reported error, an erratum may be posted on this page, to be fixed in subsequent editions of the Standard or related specifications.

Formal corrigenda notices for the Unicode Standard can be found at Corrigenda to the Unicode Standard. Corrigenda for the Unicode CLDR are posted at Unicode CLDR Corrigenda. Errata notices for Unicode CLDR and its related specification, UTS #35: Locale Data Markup Language (LDML) can be found in the various release notes accessed from the Unicode CLDR Downloads page.
