 == Test Report

 Patch tested:
 https://core.trac.wordpress.org/attachment/ticket/31992/31992-icann.patch

 === Steps to Test
 1. In WP admin, navigate to ''Users > Add New''.
 2. Enter a Username in standard ASCII characters (no need to confuse with
 related #5918).
 3. Enter a valid Email with extended ASCII or unicode characters, e.g.:
 `grå@grå.org`.
 4. 🐞 Observe error returned: `Error: The email address is not correct.`

 === Expected Results
 - ✅ An email with extended ASCII or unicode characters should be
 accepted.

 === Environment
 - Hardware: MacBook Pro Apple M1 Pro
 - OS: macOS 13.5
 - Browser: Safari 16.6
 - Server: nginx/1.25.2
 - PHP: 8.2.9
 - Database: SQLite
 - WordPress: 6.4-alpha-56267-src

 === Actual Results
 - ✅ The Add New User form accepts the email with special characters.
 - ❌ The email stored in the database (and subsequently displayed on the
 page) has special characters stripped out. E.g. (also see Figure 1):
  - `grå@grå.org` => `gr at gr.org`
  - `测试5@普遍接受-测试.世界` => `` (empty!)

 === Supplemental Artifacts
 ''Figure 1: Emails stored in database from test samples.''
