MySQL 8.x - character set utf8mb4 supported?


i have read the document, it states:

Unicode characters are properly handled provided the database was created with Unicode support in VARCHAR and CHAR fields in the CREATE DATABASE command (e.g. by using utf8 character set as the default database character set in MySQL 5.5. Please note that utf8mb4 character set does not work due to different storage requirements to utf8 character set [[1](]).

is it means that utf8mb4 is still not supported in MySQL 8 by newer keycloak version (e.g. 9 / 10) ? Or this limitation only apply to MySQL 5.x?
