[jira] Commented: (LUCENE-2847) Support all of unicode in StandardTokenizer

["Steven Rowe (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-2847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12978027#action_12978027 ] 

Steven Rowe commented on LUCENE-2847:
-------------------------------------

JFlex generates fine, everything compiles, all tests pass.

If we add a target in {{modules/analysis/icu/build.xml}} to run {{GenerateJFlexSupplementaryMacros#main()}}, maybe named {{gen-stdtok-supp-macros}}, the {{jflex}} target in {{modules/analysis/common/build.xml}} could use a {{<subant>}} to call it and auto-generate {{SUPPLEMENTARY.jflex-macro}}, no?

> StandardTokenizer currently only supports the BMP.
> If it encounters characters outside of the BMP, it just discards them... 
> it should instead implement fully implement UAX#29 across all of unicode.
