Hi, as WP 4.2 and above change the charset and collation to -> utf8mb4_unicode_ci
would it be optimal and everything will work ok if I change the plugin charset (latin1_swedish_ci) to utf8mb4_unicode_ci?
I recommend making a back-up first in case something goes wrong. I don’t think you will notice any difference, as most search tables are used only on the back-end.
