function domainToUnicode
Usage in Deno
```typescript import { domainToUnicode } from "node:node__url.d.ts"; ```
domainToUnicode(domain: string): string
Returns the Unicode serialization of the `domain`. If `domain` is an invalid
domain, the empty string is returned.
It performs the inverse operation to [domainToASCII](../.././node__url.d.ts/~/domainToASCII).
```js
import url from 'node:url';
console.log(url.domainToUnicode('xn--espaol-zwa.com'));
// Prints español.com
console.log(url.domainToUnicode('xn--fiq228c.com'));
// Prints 中文.com
console.log(url.domainToUnicode('xn--iñvalid.com'));
// Prints an empty string
