Oh, hm, you know you learn something new every day, and this is my new
thing for today.  As much as I've read RFC 2045 over the years, I missed
this!  (This is in §6.8, in case others want to look it up).

So that suggests to me that we are in fact NOT being RFC-conforming with
this behavior, and we should just silently ignore the bad characters.
Does anyone disagree with this interpretation?
