Regex give me a positive when it should be negative

[trenyture]

I have a user who could register in our database while his email is not a valid one : ĥenry@gmail.com

When I tested it, the regex said it's a valid one when it should not...

> await validate({ email: "ĥenry@gmail.com", validateRegex: true, validateMx: true, validateTypo: true, validateDisposable: true, validateSMTP: false })

{
  valid: true,
  validators: {
    regex: { valid: true },
    typo: { valid: true },
    disposable: { valid: true },
    mx: { valid: true },
    smtp: { valid: true }
  }
}

There are UTf-8 emails and they are technically valid (I have one and it is very finicky to work with but are valid), however they are almost never useful (nor do I think this library handle it correctly in the SMTP validation by checking required extensions), HTML <input> and many email providers don't take them.

I have a stricter patch that aligns more to the standards of expectation for web development in #92.
