I hesitate to even mention it again, especially as it doesn't support
the side I'm favoring here :-), but UTF-8 is not always reversible.

As I wrote earlier:

In practice, this probably wouldn't happen often, and more
importantly, I think people will rarely if ever be in the position of
actually having to recover an original bit-string from UTF-8 anyway.
But we just can't promise that it's always recoverable.
