I have been able to reproduce this issue consistently. Please refer to the
steps below to test in other environments.
> **Important note:** Please view this comment/ticket in **Firefox** (I'm
using macOS) to most easily identify the character in question. The
replacement character] will be collapsed/hidden in Safari, and display as
a blank space in Chrome, making following this ticket more difficult.
== Copying the `￼` Character ==
In Firefox, this character will appear visually as

described as the letters `OBJ` inside a box with a broken outline.
The following section includes text blocks and styled headings that can be

== Viewing the Copied Contents ==
@dmsnell has provided a [https://dmsnell.github.io/ghpages/clipboard.html
browser-based Clipboard Viewer utility] that displays the contents of the
clipboard. Take particular note of the `text/html` content, and how
elements may wrap the character depending on the copy source.
== Testing Instructions ==
=== Steps to Reproduce
1. From WP admin navigate to ''Posts > Add New''.
2. Enter a title for the post.
3. From the "Copying the `￼` Character" section above, select and copy a
`￼` character from either of the H1 or H2 styled text blocks. ''This will
copy the character with HTML as part of the pasteboard content.''
4. To verify that the `￼` character was copied with HTML, paste into the
[https://dmsnell.github.io/ghpages/clipboard.html Clipboard Viewer page]
and refer to the `text/html` row. It should include a wrapping `<h1>` or
`<h2>` tag (the character will appear as a blank space between tags).
5. 🐞 In the post, paste the character at the end of the title field. An
unexpected margin will appear below the title.
6. 🐞 Move the cursor to the start of the title and paste the character
again. An unexpected margin will appear above the title.
7. Click **Publish** (and **Publish** again if pre-publish checks are
8. 🐞 Observe that the post title is surrounded by `￼` characters.
9. 🐞 Copy the post address and observe that the slug name is wrapped with
the UTF-8 character code (`%ef%bf%bc`), e.g. `.../%ef%bf%bctest-
10. Optionally hover over the **View Post** button and observe that the
preview URL (bottom left of browser) includes the Unicode character code
(`%uFFFC`), e.g. `.../%uFFFCtest-trac-55117%uFFFC/`.
11. Optionally click to view the post and observe that the URL in the
address bar includes the URL-encoded characters from Step 9.
=== Expected Results
- ✅ Pasting text that may include the `￼` character should not affect
styling of the title field in the editor.
- ✅ The `￼` character should not appear in the title of a published post.
- ✅ The `￼` character should not be part of the post slug, encoded or
