Version 6.2.0 has been superseded by the latest version of the Unicode Standard.
Unicode 6.2.0 is a minor version of the Unicode Standard. This page summarizes the important changes for the Unicode Standard, Version 6.2.0. In the discussion below, Version 6.2.0 may be abbreviated as "Unicode 6.2" or "Version 6.2."

Version 6.2 of the Unicode Standard is a special release dedicated to the early publication of the newly encoded Turkish lira sign. This version also rolls in various minor corrections for errata and other small updates for the Unicode Character Database. In addition, there are some significant changes to the Unicode algorithms for text segmentation and line breaking, including changes to the line break property to improve line breaking for emoji symbols.
For detailed property changes see Section F. Unicode Character Database Changes.
Two other important Unicode specifications are maintained in synchrony with the Unicode Standard, and have updates for Version 6.2:
This version of the Unicode Standard is synchronized with ISO/IEC 10646:2012, plus the accelerated publication of a single character: U+20BA TURKISH LIRA SIGN.
B. Version InformationVersion 6.2 of the Unicode Standard consists of the core specification, the delta and archival code charts for this version, the Unicode Standard Annexes, and the Unicode Character Database (UCD).
The core specification gives the general principles, requirements for conformance, and guidelines for implementers. The code charts show representative glyphs for all the Unicode characters. The Unicode Standard Annexes supply detailed normative information about particular aspects of the standard. The Unicode Character Database supplies normative and informative data for implementers to allow them to implement the Unicode Standard.
Version 6.2.0 of the Unicode Standard should be referenced as:
The Unicode Consortium. The Unicode Standard, Version 6.2.0, (Mountain View, CA: The Unicode Consortium, 2012. ISBN 978-1-936213-07-8)
http://www.unicode.org/versions/Unicode6.2.0/
A complete specification of the contributory files for Unicode 6.2 is found on the page Components for 6.2.0.That page also provides the recommended reference format for Unicode Standard Annexes.
The navigation bar on the left of this page provides links to both the core specification as a single file, as well as to individual chapters, and the appendices. Also provided are links to the code charts, the radical-stroke indices to CJK ideographs, the Unicode Standard Annexes and the data files for Version 6.2 of the Unicode Character Database.
Code ChartsSeveral sets of code charts are available. They serve different purposes:
For Unicode 6.2.0 in particular two additional sets of code chart pages are provided:
The delta and archival code charts are a stable part of this release of the Unicode Standard. They will never be updated.
ErrataErrata incorporated into Unicode 6.2 are listed by date in a separate table. For corrigenda and errata after the release of Unicode 6.2, see the list of current Updates and Errata.
C. Stability Policy UpdateA property value constraint has been added to guarantee that no new characters will be added to the standard with Decomposition_Mapping values whose first character has a non-zero Canonical_Combining_Class. There are four exceptions, which were encoded long ago, prior to Unicode 2.1.
D. Textual Changes and Character AdditionsNote: The Unicode Character Encoding Stability Policy restricts possible future changes to the Unicode Standard, but is not formally a part of the standard itself.
Textual changes are very minimal in this version, and are essentially limited to adding a description for the new Turkish lira sign.
Character Assignment OverviewOne new character assignment was made in the BMP for the Unicode Standard, Version 6.2. This addition brings the total number of characters assigned in the standard to 110,117. (That is the traditional count, which totals up graphic and format characters, but omits surrogate code points, ISO control codes, noncharacters, and private-use allocations.)
No new blocks are defined in Version 6.2.
E. Conformance ChangesThere are no significant conformance changes in the core specification. However, there are minor changes to the text segmentation algorithms in UAX #14 and UAX #29.
F. Unicode Character Database ChangesThe detailed listing of all changes to the contributory data files of the Unicode Character Database for Version 6.2 can be found in UAX #44, Unicode Character Database.
Segmentation properties (Grapheme_Cluster_Break, Word_Break, Line_Break) have been modified to improve the segmentation of regional indicator symbols. Other modifications have been made to the Line_Break property values for pictographic symbols, to enable better line breaking behavior. A number of small corrections have also been made for numeric, East Asian width, script, and Unihan properties, and one name alias correction has been added.
Starting with Version 6.2, the encoding for the Unicode names list file (NamesList.txt) has been changed from Latin-1 to UTF-8. This change became possible because of an update of the charting tools which use the names list file in the production of the Unicode code charts.
The U-Source data and glyphs associated with UAX #45 have been added to the Unicode Character Database.
The Script_Extension property was changed from provisional to informative.
G. Unicode Standard Annex ChangesIn Version 6.2, many of the Unicode Standard Annexes have had significant revisions. The most important of these changes are listed below. For the full details of all changes, see the Modifications section of each UAX, linked directly from the following list of UAXes.
