Let's bound the problem a bit here.  MTAs wouldn't normally care about
this, since this only appears in the display-name and it wouldn't even
have been visible until the after the DATA command had finished.  I can't
really think it would be reasonable for an MTA to reject email for that
reason by that point, so I think it's reasonable for the burden to fall
on the MUA to make sense of this.
