That's not true: there are actually *two* facilities that allow exactly that.
1. you can write a new codec which round-trips these bytes through
some characters,
2. you can write an error handler that does such round-tripping. The
    surrogate-escape error handler was specifically designed to allow such
    round-tripping, see
    (not just for this codec, but for any codec).
