> 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/}}
