Subject: Interest in Faster Unicode Normalization

Hi, pgsql-hackers!

I've been working on a project for some time now that implements
Unicode normalization (NFD, NFC, case fold, etc.) at high speed using
SIMD instructions. The results are promising, and you can check out
the benchmarks over ICU: https://github.com/dzfrias/xxUTF#benchmarks.
I also saw a push for faster normalization in this mailing list,
https://www.postgresql.org/message-id/844d3dd7-2955-4794-95d1-7f4c13cb89fc%40gmail.com. 

I was wondering if Postgres was interested in this work. I know that
my project is an early-stage library, but I think it could be of use
to Postgres in some way or another. Is there any way I could apply my
work to help Postgres? I’ve been working on this project for a while
and honestly just want to see if any larger open source projects are
interested.

Best,
Diego Frias
