Subject [jira] [Created] (LUCENE-4072) CharFilter that Unicode-normalizes input
Date Tue, 22 May 2012 02:07:41 GMT
Ippei UKAI created LUCENE-4072:
----------------------------------

             Summary: CharFilter that Unicode-normalizes input
                 Key: LUCENE-4072
                 URL: https://issues.apache.org/jira/browse/LUCENE-4072
             Project: Lucene - Java
          Issue Type: New Feature
          Components: modules/analysis
            Reporter: Ippei UKAI


I'd like to contribute a CharFilter that Unicode-normalizes input with ICU4J.

The benefit of having this process as CharFilter is that tokenizer can work on normalised
text while offset-correction ensuring fast vector highlighter and other offset-dependent features
do not break.

The implementation is available at following repository:
https://github.com/ippeiukai/ICUNormalizer2CharFilter

Unfortunately this is my unpaid side-project and cannot spend much time to merge my work to
Lucene to make appropriate patch. I'd appreciate it if anyone could give it a go. I'm happy
to relicense it to whatever that meets your needs.
