Many (most) web forms reject my RFC-822 valid email address:
Paul Gilmartin <PaulGBoulder@********.tld>
when I copy-and-paste it from my email header.
And they force the local-part to monocase, violating the RFC.
And my phone, copied from my Contacts entry:
(720) 382-xxxx
They accept only digits. Some add insult to injury by then reformatting
it as I had tried to enter it.
And credit card numbers with groups of 4 digits.
