Updates and Errata
The following is a list of errata noted for
Standard, Version 13.0, its code charts, annexes, the Unicode
Character Database, and the text and data files for other synchronized
specifications. It is periodically updated to include
corrections to typographic errors and new clarifications of the
text. This list also includes errata noted for the text of The Unicode Standard, Version 13.0—Core Specification.
Current Errata Notices
EastAsianWidth.txt for Version 13.0 has a typo in its internal date. The date for Version 13.0 reads:
# Date: 2029-01-21, 18:14:00 GMT [KW, LI]
The intended year in that date was 2020.
In Version 13.0 of UAX #38, Unicode Han Database (Unihan), there are errors in the regular expressions for three of the IRG source properties.
The second line of the pattern reads:
The correct value should be:
The third line of the pattern reads:
The correct value should omit the final, unmatched parenthesis:
The pattern reads:
The correct value should be:
These patterns will be corrected in a future version of UAX #38.
The code chart for the Wancho script published in the Unicode Standard for
Versions 12.0 through 13.0 used a preliminary font with a sub-optimal design for the
script. That font for the Wancho script will be replaced in a future version of the
standard by an updated font provided by Banwang Losu, as documented in L2/20-121.
Section 11, Searching and Matching
in Version 13.0 of UTS #10, Unicode Collation Algorithm
contains a small but significant pair of typos in one part of the statement of
step DS4a. Sub-step 4 of DS4a currently reads:
4. Find the largest e' ≥ e such that Q[e',e'] is canonically equivalent to P[n', n'] for some n'.
Each of those substring notations as currently written represents an empty string. The correct,
intended text should be:
4. Find the largest e' ≥ e such that Q[e,e'] is canonically equivalent to P[n, n'] for some n'.
This pair of typos has been in the text of DS4a for a number of versions, since a mistake in
the final editing of Version 9.0.0. It will be corrected in a future version of UTS #10.
Blocks.txt for Version 13.0 has a typo in the code point
for the end of the range of the Tangut Supplement block. The
entry for Version 13.0 reads:
18D00..18D8F; Tangut Supplement
In a future version of the standard, that typo will be
corrected to reflect the intended range for the block:
18D00..18D7F; Tangut Supplement
This corrrection also implies the need for corresponding updates to one comment line
and one data line in VerticalOrientation.txt:
# Khitan Small Script & Tangut Sup: U+18B00..U+18D8F
18D09..18D8F ; U # Cn  <reserved-18D09>..<reserved-18D8F>
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.
