What do you mean "by default"?  It was quite explicit in the code I
posted, and it's the only reasonable thing to do with "text data
without known (but ASCII compatible) encoding or multiple different
encodings in a single data chunk".  If you leave it as bytes, it will
barf as soon as you try to mix it with text even if it is pure ASCII!
