Does it work for for char -> wchar, too?
It does not. 0xffff is a valid code point, and I think so are all the
other values that would result. In fact, I think there are no invalid
code units for wchar.

U+ffff would be fine, better at least than a surrogate.
U+ffff is still a valid code point, even if it's not assigned any
unicode character.
But the result would be U+ff80 to U+ffff, and I'm sure some of those are
valid code points.
