I'm wondering if this boils down to a question of what the 1.0 behaviour
will be. I'm pretty convinced that the email-like is the way to go, but
it does require some changes to the existing codebase.

Is this something that should be part of the I18N work that will be done
after 1.0? How much of the desire for UTF-8 is really a desire to get
1.0 out the door?
