This also ties into Unicode email addresses, which currently has a patch
with a single (negative) review on SF and still has had 0 comments in
this forum despite being brougt up twice before:

I suspect this already handles most of this, except for better splitting
and validation of the domain part. If nothing else, any address
vaidation work should use it as an example on how to translate between
Unicode and ASCII email address representations.
