[Koha] Request for documentation -- ICU chains

[Barton Chittenden]

I did a bit of searching for ICU chains documentation on the Koha wiki,
based on Fatone's post 'local language searching problem' ... and I wasn't
really satisfied with what I found:

The most complete documentation that I found was here:

https://wiki.koha-community.org/wiki/Correcting_Search_of_Arabic_records

There's also

https://wiki.koha-community.org/wiki/Correcting_Search_of_Polish_records

I've added https://wiki.koha-community.org/wiki/ICU_chains_configuration

but I'm not enough of an expert to explain how to set up transliterate
rules, which seem to be an important part of getting ICU to work to its
fullest potential.

Thanks,

--Barton
