In this context, we can assume the target buffer multibyte.

Pmail uses seperate buffers unlike Rmail, as Paul indicates in
<48D33A10.4040102@pajato.com>.  Let us call the one buffer holding raw
contents of mbox file A, and another displaying a message B.

I think the most straightforward way is to do:

1. set the buffer A unibyte
2. set the buffer B multibyte
3. extract a message body from A into a string
4. decode the string
5. insert it to B

and the only drawback is inefficiency (if it is measurable).

The term "multibyte binary" looks like an oxymoron for me ;-)
