Ok, working under the assumption you need to provide it a string, it still
leaves the question why adding the header after the fact (to a string input)
does not produce the same result as declaring the encoding type inline.

I find this limitation hard to believe, why bother with encoding flags if it
can only ever accept ASCII anyway?
The reason this issue came up was because I was adding the header after like in
my examples and it wasn't working, so I Google'd around and found this
Stackoverflow:
http://stackoverflow.com/questions/10295530/how-to-set-a-charset-in-email-using-smtplib-in-python-2-7
Which seemed to be doing exactly what I wanted, with the only difference is the
inline deceleration of utf-8, with that change it started working as desired...
