How do I wrap Python 3's io.BytesIO() with surrogateescape decoding?

Question

I've found Python3's open("filename", "r", encoding="ascii", errors="surrogateescape") to be useful. How do I wrap an io.BytesIO() (or any not-a-real-file source of bytes) to create a text-mode file-like object with the same decoding behavior?

Answer 1

That's what TextIOWrapper does.
