Comment (by kimjiwoon):

 **Reply to @peterwilsoncc**

 The issue appears to be resolved on my WordPress sites — the England,
 Scotland, and Wales flags are now rendering correctly on Windows where
 they previously appeared as 🏴 black flags.

 However, in the WordPress Core Trac interface, these emojis still render
 as black flags on Windows.
 This suggests the fix may be environment-specific (possibly front-end
 Twemoji fallback working, but not in Trac's rendering).

 Were there any related patches in the past three months?
 Could the recent ActivityPub plugin patch regarding multibyte character
 handling be related?

 그 흐름이면 이렇게 정리해서 보고하는 게 깔끔하겠습니다.

 Tested with the following flag emojis using ActivityPub and Mastodon:

 *
 ![🏴](https://s.w.org/images/core/emoji/16.0.1/svg/1f3f4-e0067-e0062-e0065-e006e-e0067-e007f.svg)
 (England)

 (Scotland)

 ![🏴](https://s.w.org/images/core/emoji/16.0.1/svg/1f3f4-e0067-e0062-e0077-e006c-e0073-e007f.svg)
 (Wales)

 Steps:

 1. Posted a comment from Mastodon to a WordPress site with ActivityPub
 enabled → emojis rendered correctly on the front-end.
 2. Copied the same comment content and posted it manually on a self-hosted
 WordPress site → emojis rendered correctly as well.

 This suggests that at least in front-end rendering (both ActivityPub-
 federated and manual comment posts), Twemoji fallback works properly now.

 However:

 * In WordPress Core Trac, the same flag emojis still render as 🏴 black
 flags on Windows.
 * Possibly unrelated, but on WordPress.com the block editor is enabled for
 comments, and when inserting these emojis there, they are sometimes added
 as image elements instead of Unicode characters.
