Controversial UTF-8 characters

[1oglop1]

Hi, I was comparing this crate with validator crate, you mentioned in #16.

And I have an email with a controversial character � - https://en.wikipedia.org/wiki/Specials_(Unicode_block)
Then email_address and validator do not agree if it is valid or notabc�def@example.com

let email = "abc�def@example.com";
EmailAddress::from_str(email).is_ok(); // true
validator::validate_email(email);  // false

At the moment this crate allows valid email with UTF8 - I guess that's according to

• https://datatracker.ietf.org/doc/html/rfc6531#section-3.2
• https://en.wikipedia.org/wiki/Email_address#Local-part

perhaps this could be part of parse_with_options suggested in #20.

Probably the best thing for the community would be to have just one crate for email validation.

This is a defect. The is_uchar test was way to permissive. Have replaced it with is_utf8_non_ascii as it should be. Release soon.
