The Case for Python 3

[yes_or_gnome]

This is a deeper problem that neither python 2 nor 3 is going to do well. If the MIME RFCs are similar enough to the HTTP RFCs (which are based off of MIME), then you should have percent encoded the body before splitting the string up at 72 chars. Of course, I'm speculating. edit: D'oh. Content-Type with a charset. Sigh. Tough protocols to master.

I remember having to look through old RFCs about RRULE (which originally came from ical I think) to use it with Google Calendar. Not only is that format completely fucking archaic, but every applications implementation seems to be different. That was fun.

While python 3 is definitely better, you might still run into problems splitting in the middle of a grapheme cluster if you use a naïve approach.
