Hi!
I get 'latin1' when running the MariaDB client in a clean install:
```
± docker run -it -v ${PWD}:/build -w /build debian:sid bash
root@eb0c4013a610:/build# apt update
root@eb0c4013a610:/build# apt install -y mariadb-server
...
Processing triggers for mariadb-server (1:10.11.5-3) ...

root@eb0c4013a610:/build# mysql -e '\s'

I am not sure where latin1 (or utfmb3 in your case) is inherited from.
We could consider adding utfmb4 in
https://salsa.debian.org/mariadb-team/mariadb-server/-/blob/debian/latest/debian/additions/mariadb.conf.d/50-client.cnf
to ensure if is used by default by clients as well in Debian.
We might also want to adopt
https://github.com/MariaDB/server/commit/0e8dfcfd421ebcb8dc13b4660cd3e6c6fbce2023
in Debian already with 10.11 and not wait for 11.3.
