To answer the question that appeared at the end of the original message,
X.400 should not have any problems in this respect.  X.400 messages are
binary data structures, and the protocols between mailer processes are
also binary messages.  There is no text parsing involved.  For instance,
rather than having a mailer daemon transmit Character strings are
encoded as a type word followed by a length byte followed by the
specified number of characters (I am purposely simplifying, leaving out
things like the character set identifier).  No ambiguity is possible
within the protocol (of course, user interfaces are another problem, as
they must translate between this form and printed form).
