mosh does require locale support. It's possible you could build locale 
support only into the mosh binary, and not the rest of the system, though 
that would be a hack as mosh expects all terminal output to be in UTF-8.

Try "ssh thebox -tt ls /". This will force a pty allocation, and possibly 
trigger the same error.
