IIRC it can make a difference w.r.t line-endings.

It's definitely not wrong for unibyte buffers where there's no "internal
representation of characters" that can spill out ;-)

And AFAIK it's not wrong for multybyte buffers:
- Either the content of the buffer is limited to ascii and eight-bit
  chars in which case the output is exactly right.
- Or there are other chars and there is simply no correct output.
  We should likely signal an error in this case, tho we probably just
  end up exposing the internal utf-8-like encoding instead, indeed.
  Still the error is not necessarily in the use of `binary` in that case
  but in the actual content of the buffer.
