[jira] [Commented] (LUCENE-8125) emoji sequence support in ICUTokenizer

["Robert Muir (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-8125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16317274#comment-16317274 ] 

Robert Muir commented on LUCENE-8125:
-------------------------------------

Note: I think it'd be nice to fix for standardtokenizer at some point too, but we need to first bring its grammar up to the latest unicode i think? This way it will have the latest uax#29 rules around this stuff such as "Do not break within emoji zwj sequences." So some work to do for that, but we can tackle here with ICU first.

> uax29 word break rules already know how to handle these correctly, we just need to assign them a token type. 
> This is better than users trying to do this with custom rules (e.g. LUCENE-7916) because they are script-independent (common/inherited).
