I forgot to address this point, sorry.  U+FFFD is, IME, commonly used 
when encountering a decoding issue and aborting is not an option.  It 
could be used as a hint on the decoding side that there was an error in 
the original decoding of the message, although I'm not sure how many 
people are gonna check for it.  A '?' is a better option on user-facing 
programs.

Given this, I think both can work out well in practice, and will be 
happy to change the U+FFFD REPLACEMENT CHARACTER to a '?' if preferred.
