I never said it did.  It just happens to be the context with which I am
working.  I said I wanted to concatenate materials without regard for
the character set.  I am mixing binary data with ASCII and Unicode, for
sure, but I should be able to do this.

The current source can be found at
http://fd0man.theunixplace.com/scrapbook.py which is the version that I
am having the problem with.

I am not saying anything about Python's standard library.  Furthermore,
I am not using MIME e-mail.  The MIME component that I am using, which
should be ideal for me, builds the message just fine—when not using a
binary component.  I am looking for how to tell Python to combine these
objects as nothing more than a stream of bytes, without regard for what
is inside the bytes.  That is what I was asking.  You did not tell me
how to do that, or if that is even possible, so why flame me?  I am not
saying "Python is bad, evil!" and blaming it for my ignorance, but what
I am asking for is how to accomplish what I am attempting to accomplish.
The MIME component is a (slightly modified) version of the recipe
provided from the ASPN Python Cookbook.

In short:  How do I create a string that contains raw binary content
without Python caring?  Is that possible?

    Thanks,
    Mike
