Version 4.1 of UCA Released:
Searching, Sorting, and Matching Unicode Characters
Mountain View, CA, May 6, 2005 - The Unicode Consortium announced today
the release of Version 4.1.0 of UTS #10, The Unicode Collation Algorithm
(UCA), used for searching, sorting, and matching Unicode characters.
The major changes in this release are:
- increase in repertoire to cover the recently-released Unicode 4.1.0
- a revised handling of Thai/Lao via contractions
- enhancements to sorting and matching, with new conformance requirements
- changes to the handling of ignorable characters
- guidelines on the use of grapheme joiner
- additional introductory text
- changes in weights for a small number of characters.
The UCA also serves as the basis for collation in the Common Locale Data
Repository (CLDR); the language-specific collation sequences in the CLDR
are expressed as tailorings of the default UCA table. For more information,
