Entering … or pasting it into the terminal is not possible.

Hmmm, the ssh server doesn't have PAM enable. And it can't be enabled. sshd_config(5): "If UsePAM is enabled, you will not be able to run sshd(8) as a non-root user. The default is no."

For normal ssh connections, we set LC_CTYPE DEFAULT=en_US.UTF-8 via /etc/security/pam_env.conf via pam_env via /etc/pam.d/sshd.

We can just hardcode that into mxqi. Or would it be cleaner to forward it from the client?

I guess forwarding it is cleaner, but until now nobody but me asked for it. So hardcoding it, if much easier, should be enough.

Merci! Works for me.

(My test was incorrect, and mxqi would have needed to be updated on stairwaytoheaven.)
