Subject [jira] Created: (LUCENE-2699) Update StandardTokenizer and UAX29Tokenizer to Unicode 6.0.0
Date Wed, 13 Oct 2010 04:31:34 GMT
Update StandardTokenizer and UAX29Tokenizer to Unicode 6.0.0
------------------------------------------------------------

                 Key: LUCENE-2699
                 URL: https://issues.apache.org/jira/browse/LUCENE-2699
             Project: Lucene - Java
          Issue Type: Improvement
          Components: contrib/analyzers
    Affects Versions: 3.1, 4.0
            Reporter: Steven Rowe
            Assignee: Steven Rowe
            Priority: Minor
             Fix For: 3.1, 4.0


Newly released Unicode 6.0.0 contains some character property changes from the previous release
(5.2.0) that affect word segmentation (UAX#29), and JFlex 1.5.0-SNAPSHOT now supports Unicode
6.0.0, so Lucene's UAX#29-based tokenizers should be updated accordingly.

Note that the UAX#29 word break rules themselves did not change between Unicode versions 5.2.0
and 6.0.0.
