Copy and paste U+202A
To copy and paste LEFT-TO-RIGHT EMBEDDING (U+202A), press the button: the character itself goes to your clipboard, and Ctrl+V (Cmd+V on a Mac) pastes it anywhere you can type.
Careful: this is a bidirectional control. Pasted into a file name, a message or source code, it can make the text display in a different order from the one it is stored in.
Where it comes from
Older software that formatted mixed-direction text before the isolate characters existed, and from copy-paste out of such software.
Why it matters
Embeddings nest and leak. An unterminated one applies to the rest of the paragraph, and because they are invisible, a stray embedding is one of the hardest formatting bugs to find by eye.
Before and after
An embedding and its pop, both invisible, wrapped around one word.
The character is shown as a labelled chip so you can see where it sits. In your text it draws nothing at all.
When it is legitimate
It was the right tool before Unicode 6.3. Since then the isolates (U+2066-U+2069) do the same job without letting the effect escape into neighbouring text, and Unicode recommends them instead.
How to remove it
The default pass removes it. Ghostchars removes all five of U+202A-U+202E without asking, because none of them can be verified as correct from the text alone.
Working in a file rather than a paste? The document report for .docx, .odt and .html finds it inside the file, together with hidden runs and tracked changes, without you having to open it. If the question is what the rest of the writing does rather than what this one character does, count the tell words and phrases per thousand words and see where each habit sits, with no score and no claim about who wrote the text.
Is it an AI watermark?
Not a watermark
No. A legacy formatting control. Finding one says the text passed through older bidi-aware software.
No connection to machine-generated text. It comes from software, from a keyboard, or from a person.
Questions
What should be used instead?
U+2066 LEFT-TO-RIGHT ISOLATE with U+2069 POP DIRECTIONAL ISOLATE. Isolates confine their effect to the span they wrap.
Why are unmatched embeddings a problem?
Because the effect runs to the end of the paragraph. Text pasted after it inherits a direction nobody intended.
