The default escape character ~ does not work if the tilde key in your keyboard layout is a dead key [1], like it is in many European layouts. It can be changed via the EscapeChar config option or the -e command line parameter. It seems, though, that not just any old character is accepted - I tried to use §, which, in the Finnish layout, is in the same physical position as ~ is in the US version, but ssh complains about "bad escape character".

EDIT - I suppose it must be an ASCII character, which is not an entirely unreasonable requirement.

It works, you'll just have to type

  <tilde> <space> .

Weird - I did try that before writing the comment and it didn't work. May depend on the terminal or something.

I use a french mac layout and it works well. But you have to type ~ then press space, then press shift+; (because shift+; is .)

This must be why mosh's escape sequence never worked for me (ctrl-^ or ctrl-^.)

Seems to be fixed (to use the same as SSH): https://github.com/keithw/mosh/issues/215

You can change what the default escape character is in the ssh config file.
