Add support for utf8mb4_0900_* collations in MariaDB Server

    XMLWordPrintable

Details

    Description

      Please add support for utf8mb4_0900_* collations in MariaDB Server. This would allow for better accent handling in text data.
      This also makes migrations from MySQL 8.0 to MariaDB easier.
      This is also a requirement for getting replication to work from MySQL 8.0 to MariaDB and MariaDB to MySQL 8.0

      The plan is to implement most of the MySQL 8.0 utf8mb4_0900 collations as alias for the MariaDB utf8mb4_1400 collations.
      This should be fine in most cases as utf8mb4_1400 is a newer version of the utf8mb4_0900 collations.
