Thanks for the ideas.
In this case, ssh, it is a transfer layer protocol, which means it
does not convert anything. For example the server was using ascii, and
the client was using ascii, then good. If the client was using UTF-8
instead, then he might get a broken display, ssh itself would not
My idea for CString is because in C, this is easy, "I" do not pay
attention to which encode the given string is using.
But I am not sure how CString works. If it just convert things into
ASCII, then it is bad.
