 **Title:**
 Flag emoji rendering issue on Windows environment

 **Description:**
 On WordPress, flag emojis for England (`🏴󠁧󠁢󠁥󠁮󠁧󠁿`), Scotland (`🏴󠁧󠁢󠁳󠁣󠁴󠁿`),
 and Wales (`🏴󠁧󠁢󠁷󠁬󠁳󠁿`) do not render correctly in Windows environments.
 Instead of showing their respective flag designs, they are displayed as a
 plain black flag (`🏴`).

 On mobile devices (such as Android or iOS), these flag emojis render
 properly as intended using either system emojis or Twemoji fallback.
 However, on Windows 10/11 desktop systems, particularly with the Segoe UI
 Emoji font, the emoji tag sequences required for these regional flags are
 not supported, causing them to appear as a generic black flag.

 **Steps to Reproduce:**

 1. Post a comment or content on a WordPress site containing these emojis:

    * 🏴󠁧󠁢󠁥󠁮󠁧󠁿 (England)
    * 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (Scotland)
    * 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (Wales)
 2. View the page on:

    * **Mobile (Android/iOS)** → Emoji display correctly
    * **Windows 10/11 desktop** → Displays as 🏴 black flag

 **Expected Result:**
 England, Scotland, and Wales flag emojis should render properly across
 platforms, or at least gracefully fallback via Twemoji when system font
 support is lacking.

 **Actual Result:**
 On Windows, all three flag emojis appear as 🏴.

 **Additional Info:**

 * Confirmed on latest WordPress.com and WordPress.org self-hosted sites.
 * Twemoji appears to correctly render these on other platforms like
 Mastodon, X.com (Twitter), and Misskey.
 * Possible workaround: Ensure Twemoji or another fallback emoji library
 handles emoji tag sequences on desktop platforms where system fonts lack
 support.

Comment (by dd32):

 This was rendering all Black flags everywhere, I think the emoji's were
 all black flag rather than the intended country flags. I've edited it to
 use the correct emoji flags for testing.
