XML Representation of Unicode 6.0.0 UCD This directory contains the representation in XML of version 6.0.0 of the UCD, using the schema defined by UAX 42, "Unicode Character Database in XML". While every effort has been made to ensure consistency of the XML representation with the UCD files, there may be some errors; the UCD files are authoritative. There are six files, available in zip/jar format; the size is that of the archive: flat grouped no Unihan data 599 KB 391 KB Unihan data only 5,418 KB 5,423 KB complete UCD 6,768 KB 5,814 KB The flat versions do not use the group mechanism. The grouped versions use the group mechanism, with groups corresponding approximately to the blocks (a few blocks have been subdivided). The "no Unihan data" files do not contain the properties expressed only in the Unihan database. The "Unihan data only" files contain only the properties and code points expressed in the Unihan database. The "complete UCD" files reflect the complete UCD data.
