Description
All unknown characters, including multi-byte unicode ones, after the initial backslash appear to not interrupt the input processing like known commands do.

Even more interestingly, it seems to keep both collecting the result as well as parse it for any new commands:
MariaDB [test]> \a

This results in some confusing situations where you don't know why the client expects more input when normally it would stop after a backslash command.
