--- Comment #1 from Damien Miller <djm at mindrot.org> ---
Unfortunately, allowing arbitrary characters also allows terminal
reprogramming attacks. A good solution to this would be to detect that
the terminal can handle UTF-8 characters and to validate that the
characters coming from the server consitute valid UTF-8 runes and not
VT terminal reprogramming codes.
