There are several places on the wiki that cover using ICU chains - it is much
more involved than a syspref swtich (well, it's a switch in two config files)
https://wiki.koha-community.org/wiki/ICU_chains_configuration
https://wiki.koha-community.org/wiki/ICU_do_not_undiacritic
https://wiki.koha-community.org/wiki/Correcting_Search_of_Arabic_records

ICU still doesn't work with queryfuzzy afaik

I did not find the documentation from Zebra on the use of quotes, but I assume
ICU requires the change - many of our partner sites were using non-ICU indexing
with ICU style quotes, so at least one=-way it is not harmful
