Let's make that the raw bytes by default -- we can add a parameter to
Message() to specify that the default where possible is unicode for
returned values, if that isn't too painful.
Here's my reasoning: ultimately, everyone NEEDS to understand that the
underlying transport for e-mail is bytes (similar to sockets). We do
people no favors by pasting over this too much. We can overlay
convenience at various points, but except for text payloads, everything
should be bytes by default.
Even for text payloads, I'm not entirely certain the default shouldn't be
bytes: consider an HTML attachment that you want to compare against the
output from a webserver. Still, as long as it's easy to get bytes for
text payloads, I think overall I'm still leaning toward unicode for them.
