This is almost exactly what the Plan 9 implementation does, except that it uses
a different character, on the grounds that an encoding error is not the same as
an unrepresentable character (the higher-level recovery strategy, if any,
is different). The implementers' specific choice was the (basically)
unused control character U+0080.
