Support characterEncoding and collation in jdbc

Hi, I'm wonder could we implement support for characterEncoding and collation settings in jdbc please? Mysql version has it but mariadbs doesn't. But could we make this better then mysql's by allowing setting utf8mb4 in characterEncoding. This will allow enterprise users to be able to set a connection to use a specific character encoding and charset without needing to change the db.

But could we support it as in allowing it in jdbc like for example

jdbc:mariadb://10.68.23.211/reviewdb?useUnicode=true&characterSetResults=utf8&characterEncoding=utf8mb4&connectionCollation=utf8mb4_unicode_ci

could we also support executeQuery in there so we could do SET NAME utf8mb4 in jdbc.
