when using Encode::MIME ...
encoding a string like "=?UTF-8?B?w4RwZmVs?=" into MIME-B is not possible
because none of the contained strings is being quoted and thus encoding to
MIME-B and decoding back doesn't result in "=?UTF-8?B?w4RwZmVs?=" but in
"Äpfel" instead. I fixed this by encoding \x3f, too.

Another problem is when you want to encode and immediately decode from/to
MIME-Q. This does not work because encode returns a string with utf8 flag on.
utf8 flag should be off however, encoding to MIME-B or MIME-Header returns by
the way also a string with utf8 flag off so the this looks very much like a bug
to me. The attached patch fixes this two bugs:
