Yes, it has a way of avoiding this problem.  It simply leaves the
original byte in the buffer.

Only if it's a garbled file.  A file can only be encoded one way,
anything else is random 8-bit bytes.

Yes, but that's not the wrapping I had in mind.

In Emacs 20.5, click Help->Options->Auto Fill.

For composition, yes.
