Email validation rejects email with special characters

[timheerwagen]

For example info@räucher.de gets rejected because of the "ä".

In Chrome, special characters are automatically converted to ASCII on the client side and back. However, this is not the case with Firefox and Safari. So I have no problems in Chrome browsers, but in the others.

Im using simple z.string().email(), dont want to transform each to ASCII by myself and use my own validator.

On the subject of email regexs...
I've spotted an issue with email validation if

1. there's a subdomain
2. the domain is hyphenated

const a = z.string().email();
a.parse("yo@subdomain.my-domain.com");

returns

ZodError: [
  {
    "validation": "email",
    "code": "invalid_string",
    "message": "Invalid email",
    "path": []
  }
]

Using Zod 3.21.4

Edit - looks like there's a possible fix proposed #2157

[timheerwagen]

This is my current workaround:

import { z } from "zod";
import punycode from "punycode";

export const zEmail = z
  .string()
  .transform(punycode.toASCII)
  .pipe(z.string().email());

Emails with special characters still get rejected.

EDIT: I just updated to latest (3.22.4) and that fixed this.

I have a similar issue with emails that contain multiple subdomains with the first level subdomain (closest to the domain) containing numbers.
