Well, this works great if your locale is UTF-8. But ... what happens
if your email address contains UTF-8, and your locale setting is

You get "rubout" characters or whatever. Nothing else can be done.
I think that you're asking "how do I display red when I don't have
red" and the answer is, you don't. To be really retro about it, if
I'm reading email on a VT-100 and someone includes a UTF-8 arabic
character in the email address, I'm out of luck; it can't be displayed.
Are we making a bigger issue out of this than necessary? There are
very few actual VT-100s left in the work outside of the Computer History
Museum. Most people use devices that can support Unicode. This is like
our old discussion about supporting non-Posix systems. Who gets left in
the dust if we go Unicode? Is it a significant portion of the user base?
