LUCENE-3747: finish upgrading to Unicode 6.1 (merge trunk r1387813)
> Support Unicode 6.1.0
> ---------------------
>
> Key: LUCENE-3747
> URL: https://issues.apache.org/jira/browse/LUCENE-3747
> Project: Lucene - Core
> Issue Type: Improvement
> Components: modules/analysis
> Affects Versions: 3.5, 4.0-ALPHA
> Reporter: Steve Rowe
> Assignee: Steve Rowe
> Priority: Minor
> Fix For: 4.0-BETA, 5.0
>
> Attachments: LUCENE-3747.patch, LUCENE-3747.patch, LUCENE-3747-remainders.patch
>
>
> Now that Unicode 6.1.0 has been released, Lucene/Solr should support it.
> JFlex trunk now supports Unicode 6.1.0.
> Tasks include:
> * Upgrade ICU4J to v49 (after it's released, on 2012-03-21, according to http://icu-project.org).
> * Use {{icu}} module tools to regenerate the supplementary character additions to JFlex grammars.
> * Version the JFlex grammars: copy the current implementations to {{*Impl3<X>}}; cause the versioning tokenizer wrappers to instantiate this version when the {{Version}} c-tor param is in the range 3.1 to the version in which these changes are released (excluding the range endpoints); then change the specified Unicode version in the non-versioned JFlex grammars from 6.0 to 6.1.
> * Regenerate JFlex scanners, including {{StandardTokenizerImpl}}, {{UAX29URLEmailTokenizerImpl}}, and {{HTMLStripCharFilter}}.
> * Using {{generateJavaUnicodeWordBreakTest.pl}}, generate and then run {{WordBreakTestUnicode_6_1_0.java}} under {{modules/analysis/common/src/test/org/apache/lucene/analysis/core/}}
