Robert Muir updated LUCENE-8125:
--------------------------------
Attachment: LUCENE-8125.patch
I updated with a middle of the road approach better matching our RBBI rules. I
don't think it would cause additional complexity if we wanted similar for jflex.
I still kept a TODO around the use the extended_pict set which could be used
here just like its using in RBBI rules, for maybe similar future-proofing (e.g.
we know emoji evolves rapidly and tokenizers/indexes fall behind, it would be
nice).
But I think its fair to keep as a TODO, we gotta crawl before we can run.

> 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).
