I now get this error while trying to connect to `dev.toolforge.org` with my normal environment:
```lang=shell-session,counterexample
$ mosh toolforge-dev
The locale requested by LANG=C.UTF-8 isn't available here.
Running `locale-gen C.UTF-8' may be necessary.
The locale requested by LANG=en_US.UTF-8 isn't available here.
Running `locale-gen en_US.UTF-8' may be necessary.
mosh-server needs a UTF-8 native locale to run.
Unfortunately, the local environment (LANG=C.UTF-8) specifies
the character set "US-ASCII",
The client-supplied environment (LANG=en_US.UTF-8) specifies
the character set "US-ASCII".

I can work around it with `LC_ALL=C.UTF-8`, but I’m sure it used to work with my normal locale settings, and it still works with `login.toolforge.org`.
