So I have no idea what's going on with mail forwards, but this is the
kind of stuff that happens to me all the time and I can't describe
correctly enough to file a bug.

The gist of it is that, under some weird circumstances, notmuch-emacs
(message-mode.el?) will screw up email forwards in a big time. I just
forwarded (or did I just reply? not sure) that private email to the list
to trigger that bug...

I get that from time to time. I think the key is that it's an email I
*sent* not *received*, which are somewhat different in their storage
mechanism...

The first symptom will be that, when sending, I'd get a prompt like
this:

Non-printable characters found.  Continue sending? (delete, replace, send, edit, ?): 

I never know what to answer to that, i usually just hit "send" or
"PLOKTA". Then I get two more annoying prompts, just to make sure I
really know about the bug. It also reminds me of how I speak a weird
language with weird characters and I don't belong on the american
Internet (capital I):

Message contains characters with unknown encoding.  Really send? (y or n) y
Use ASCII as charset? (y or n) y

ASSCII indeed. Anyways, what you saw is the result of that *amazing*
user experience.

I wish I knew how to fix that or make that more useful to folks who have
more of a clue than me. ;)

(and sorry for the cussin'...)
