Mathieu Marie commented on LUCENE-8366:
---------------------------------------

sorry to comment on a closed issue.
It seems to me that one file was not updated during the upgrade to 62-1.

[https://github.com/apache/lucene-solr/blob/branch_7_5/lucene/analysis/icu/src/tools/java/org/apache/lucene/analysis/icu/GenerateUTR30DataFiles.java#L66
]

With that update, running again the ant target `gennorm2`should also bring 3 new files :
* nfc.txt
* nfkc.txt
* nfkc_cf.txt

> This gives unicode 11 support.
> Also emoji tokenization is simpler and it gives a way to have better tokenization for emoji from the future.
