Replying to [ticket:26423 timgraham]:
> As discussed on the [https://groups.google.com/d/topic/django-
developers/ASBJ0ge2KYo/discussion django-developers mailing list], the
regular expressions for validating email addresses are complicated for
questionable benefit. We should simplify it to use HTML5 type="email"
validation ([http://blog.gerv.net/2011/05/html5_email_address_regexp/
possible candidate]). A deprecation may be needed to give time for
projects to add back more complex validation that they might required.
I've found another possible fix here
https://html.spec.whatwg.org/multipage/forms.html#valid-e-mail-address,
but I have tried this regex and it does not match much out of the ASCII
range. What does "HTML5" like browsers match that this regex does not?
