It also includes data files containing test data for conformance to several important Unicode algorithms. Full documentation for the UCD can be found in <a href="https://www.unicode.org/reports/tr44/">Unicode Standard Annex #44, Unicode Character Database</a>. </p> <h2><a name="Latest">Latest Version of the Unicode Character Database</a></h2> <p>All files for the <b>most up-to-date</b> version of the Unicode Character Database can be found at: <a href="https://www.unicode.org/Public/UCD/latest/">https://www.unicode.org/Public/UCD/latest/</a>. </p> <p>Files in the UCD/latest/ subdirectories are <i>unversioned:</i> they do not contain any version indicator in their file name. However, most of the data files contain a file header in a standard format, which indicates the Unicode version and the date of last revision of that file.</p> <p>The latest version of the Unicode Standard, which corresponds to the latest version of the UCD, can be found at: <a href="https://www.unicode.org/versions/latest/">https://www.unicode.org/versions/latest/</a>.</p> <h2><a name="UCDVersions">Specific Versions of the UCD</a></h2> <p>Each specific version of the UCD is available for archival access in a versioned directory. For example, the UCD for Unicode 14.0 specifically is available at:<br> <a href="https://www.unicode.org/Public/14.0.0/">https://www.unicode.org/Public/14.0.0/</a> </p> <p>The UCD for Unicode 13.0 is available at:<br> <a href="https://www.unicode.org/Public/13.0.0/">https://www.unicode.org/Public/13.0.0/</a> and so on for each earlier version of the standard. </p> <p>For access to versions of the UCD earlier than Version 4.1, the structure of the archival directories differed somewhat. For full details, see <a href="https://www.unicode.org/reports/tr44/#Directory_Structure">Unicode Standard Annex #44, Unicode Character Database</a>.</p> <p>A comprehensive list of the exact data files that make up a given version of the UCD can be found in the component lists at <a href="https://www.unicode.org/versions/enumeratedversions.html">Enumerated Versions of the Unicode Standard</a>.</p> <h2><a name="UCDinXML">The UCD in XML</a></h2> <p>The contents of each version of the UCD is also available in XML format. The XML files are in zipped format and are stored in a subdirectory for each version. For example, the XML version of UCD Version 14.0 can be found in:<br> <a href="https://www.unicode.org/Public/14.0.0/ucdxml/">https://www.unicode.org/Public/14.0.0/ucdxml/</a></p> <p>Full documentation about the XML versions of the UCD can be found in <a href="https://www.unicode.org/reports/tr42/">Unicode Standard Annex #42, Unicode Character Database in XML</a>.</p> <h2><a name="Beta">BETA Versions</a></h2> <p>During periods when a preliminary (beta) version of the standard is being released for public comment Public Beta files are available. For more information about any ongoing public betas see the <a href="https://www.unicode.org/versions/beta.html">BETA notice</a> as well as <a href="https://www.unicode.org/review/">Public Review Issues</a>.</p> <h2><a name="FTP">FTP Access</a></h2> <p>All files and directories in the Unicode Character Database are accessible both via HTTPS and FTP. For FTP access use an FTP client and anonymous access.</p> <p>For example, to access the contents of <a href="https://www.unicode.org/Public/UCD/latest/"> https://www.unicode.org/Public/UCD/latest/</a> by FTP, point an FTP client to www.unicode.org as the host, and /Public/UCD/latest as the path.</p> </blockquote> </td> </tr> <tr> <td align="center"> <hr width="50%"> <div align="center"> <center> <table cellspacing="0" cellpadding="0" border="0"> <tr> <td><a href="https://www.unicode.org/copyright.html"> <img src="https://www.unicode.org/img/hb_notice.gif" border="0" alt="Access to Copyright and terms of use" width="216" height="50"></a></td> </tr> </table> </center> </div> </td> </tr> </table> </body> </html>
