[keycloak-user] Keycloak user data encoding

Hi I have an encoding problem. By default users' data fields (e.g. first name and last name) are encoded using ISO-8859-1. People from many countries can't properly create accounts as their personal data is silently messed up. How can I fix it? * The MySQL DB receives already damaged names. By default all columns are ISO-8859-1-encoded, but manually converting them to UTF-8 doesn't help. * Manual account modification from admin console has same effect. * Change of default server (Wildfly) encoding to UTF-8 doesn't do anything.
