Upstream default value for 'collation_server' is 'latin1_swedish_ci': https://mariadb.com/kb/en/library/server-system-variables/#collation_server In Debian we have 'utf8mb4_general_ci' in https://salsa.debian.org/mariadb-team/mariadb-10.3/blob/master/debian/additions/mariadb.conf.d/50-server.cnf#L105 This topic needs more discussion before we make any changes to the default values in Debian. Hopefully we could avoid deviating from upstream and get these changes in upstream and globally changed.
