Data files for Version Zipped versions of the UCD for bulk download are available, as well. The Unicode Standard, Version The Unicode Consortium, A complete specification of the contributory files for Unicode That page also provides the recommended reference format for Unicode Standard Annexes.
For examples of how to cite particular portions of the Unicode Standard, see also the Reference Examples. Errata incorporated into Unicode For corrigenda and errata after the release of Unicode There were no significant changes to the Stability Policy of the core specification between Unicode 9.
Four new scripts were added with accompanying new block descriptions:. Most character additions are in new blocks, but there are also character additions to a number of existing blocks.
For details, see Delta Code Charts. A formal definition of "block" has been added to the Conformance chapter of the core specification for Unicode The detailed listing of all changes to the contributory data files of the Unicode Character Database for Version The changes listed there include character additions and property revisions to existing characters that will affect implementations.
Some of the important impacts on implementations migrating from earlier versions of the standard are highlighted in Section M. The most important of these changes are listed below. There are also significant revisions in the Unicode Technical Standards whose versions are synchronized with the Unicode Standard.
There are a significant number of changes in Unicode The most important of these are listed and explained here, to help focus on the issues most likely to cause unexpected trouble during upgrades. Some of these scripts have particular attributes which may cause issues for implementations. Zanabazar Square and Soyombo are complex, historic abugidas. They were modeled on Tibetan, and used to write Mongolian, Tibetan, and Sanskrit. The implementation of these scripts poses challenges, in particular for rendering.
Masaram Gondi is another newly added complex script, inspired by the Brahmi model, but with its own, distinct rendering issues. A large collection of Japanese hentaigana has been added. These are effectively historic variants of Hiragana syllables.
However, they are not encoded with normative decompositions, nor using variation sequences. For collation, hentaigana syllables do not have default weights the same as the standard Hiragana syllables they are equivalent to. Instead, they are sorted in a separate range following all the standard Hiragana syllables. The letters in the Syriac Supplement block, added for Malayalam Garshuni, include one which can be found with different joining behavior in different sources.
Shaping implementations that use Indic properties should be aware of the changes, as they may affect the rendering of the affected characters. Six Gujarati nonspacing combining marks used for transliteration of Arabic were added at the end of the Gujarati block: Some of those marks may occur in combinations with a single base letter. For example, a nukta or shadda may appear in combination with sukun over the same letter, and the two marks are usually strung horizontally.
Implementations should handle such sequences so as to avoid unintended visual overlapping. As a result of this change, there will no longer be word boundaries between alphabetic letters and adjacent phonetic modifiers from that set. Implementations of text segmentation will find fewer word boundaries in the affected sequences.
Such sequences are, however, rare edge cases in standard language orthographies, and are mostly found in specialized transcription systems. The UCD properties for line breaking and text segmentation have dependencies on properties of emoji characters specified in Version 5. Implementations should be aware of changes in line breaking and text segmentation behavior for some of the emoji symbols in Unicode Some of those changes had been introduced in UTR 51 Version 4.
For line breaking, the characters that appear as bases in valid emoji modifier sequences as of Version 5. That change leads to the introduction of line breaking opportunities after those two characters. The change reflects the new use of those symbols in valid emoji zwj sequences for genders and roles; the change prevents grapheme cluster and word boundaries between a ZWJ character and each of those symbols. For the latter, UnicodeData. CJK Extension F contains mostly rare characters, but also includes a number of personal and placename characters important for government specifications in Japan, in particular.
There have been significant changes to StandardizedVariants. The latter is a new data file accompanying Version 5. New emoji and text presentation sequences are also included in emoji-variation-sequences. Implementations should be prepared to consume such sequence data from the new file and, in general, to use Unicode Emoji Version 5.
Other changes in StandardizedVariants. These changes are reflected in the Unicode code charts. The documentation file StandardizedVariants. Representative glyphs for the standardized variation sequences are still shown in the Unicode code charts, but emoji and text presentation sequences are now displayed in the emoji charts, instead.
Several new data files have been added to the UCD. Implementations which parse the UCD files may need to be adjusted, depending on whether they require this new data or not. The file format is similar to the format of the Unihan data files and TangutSources. Starting with Version The file format has not changed, but certain lines of data have been updated for consistency with other UCD files.
This file provides a complete listing of the formal Name property values of characters. In the case of algorithmically derived names, only those names that follow a simple pattern of a prefix followed by a code point value are abbreviated.
The names of Hangul syllable characters, as well as all other character names, are listed individually. Implementations can use this file to conveniently retrieve the formal character names instead of independently deriving the names. This property is referenced in the line breaking and text segmentation algorithms, to assist in the determination of correct text boundaries around emoji flag sequences.
There are numerous changes in the representative glyphs, some backed by explicit errata. There are also glyph changes in the text presentation of a number of emoji and emoticons. Some of those changes reflect an attempt to make the text presentation glyphs for emoji converge on common practice among vendors for the emoji presentation glyphs. Such glyph changes are highlighted in violet in the delta charts for Version Updated the table in Section 2.
Strengthened the recommendation to use tailorings based on CLDR rules and emoji properties, for improved line breaking behavior of emoji zwj sequences. Made corrections to descriptions of ID and NS classes. UAX 31 Unicode Identifier and Pattern Syntax Withdrew the table of aspirational use scripts, moving the contents to the table of limited use scripts, and added a note explaining the reason.
Updated the discussion of immutable properties and the list of those properties in Table Added new Section 5.
Added discussion of new data file DerivedName. Added new Section 2. Updates to contents and status values. Unicode Technical Standard Changes UTS 10 Unicode Collation Algorithm The specification underwent a major rewrite to add formal definitions and to clarify the statement of the main algorithm.
The rewrite did not change the algorithm itself or the expected results for any given input data and version level of DUCET. UTS 39 Unicode Security Mechanisms Removed references to aspirational use scripts because that category has been merged with limited use scripts. Implementations which parse the UCD files may need to be adjusted, depending on whether they require this new data or not.
