About the Unicode Character Database

The Unicode Character Database (UCD) consists of a number of data files listing character properties and related data along with a documentation file that explains the organization of the database and the format and meaning of the data in the files.

Latest Version of the Unicode Character Database

All files for the most up-to-date version of the Unicode Character Database can be found at: http://www.unicode.org/Public/UNIDATA/.

Files in the UNIDATA directory are unversioned: they do not contain any version indicator in their file name. However, where a file header is present, it indicates the UCD version for which that file was last revised.

Specific Versions of the UCD

Whenever the Unicode Character Database gets updated, an update directory is placed in this directory: http://www.unicode.org/Public/

Each update directory includes only those files that were changed from previous updates. Files in the update directory are versioned: they contain a version indicator in their filename.

Getting all Files for a given Version of the UCD

The complete set of all files for a given version of the UCD consists of the files in the update directory for that version, together with all the files unchanged from earlier versions, which are kept in their respective update directories.

For a comprehensive list of all files that make up a given version of the UCD, look for the Unicode Character Database section of a given version in the Versions of the Unicode Standard.

BETA Versions

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 BETA notice as well as Public Review Issues.
