Interestingly, if you remove the "~n", it seems to work.

That is, all of these work on my R10B:

> erl_call -v -sname  -a 'io format [user,"hello\n",[]]'
> erl_call -v -sname  -a 'io format [user,hello,[]]'
> erl_call -v -sname  -a 'io format [hello]'
> erl_call -v -sname  -a 'io format ["hello"]'

but as soon as there's a tilde in there, nothing happens.
