Line separators
LINE SEPARATOR (U+2028)
Unicode’s own "new line here" character, distinct from the ASCII line feed. It ends a line without ending a paragraph.

Where it comes from
Shift+Enter in most word processors and page-layout tools, and from anything that exports from them. macOS text editors and InDesign are prolific sources.
Why it matters
It is a line break that most line-oriented software does not recognise. Files split into the wrong number of lines, CSV rows merge, and — famously — a raw U+2028 inside a JavaScript string literal used to be a syntax error, which broke JSON embedded in HTML.
Before and after
A line break your text editor may not count as one.
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
Inside a paragraph that genuinely needs a soft line break, in software that understands it. In plain text a line feed is safer and means the same thing to a reader.
How to remove it
Turn on Line endings (`-n`) and it is folded to a plain LF, along with CRLF, CR, NEL and U+2029.
Is it an AI watermark?
Not a watermark
No. It comes from word processors and layout tools. Finding one tells you the text passed through a rich text editor.
No connection to machine-generated text. It comes from software, from a keyboard, or from a person.
Questions
Why did it break my JavaScript?
Before ES2019, U+2028 and U+2029 were not allowed unescaped in string literals, so JSON embedded directly in a script tag could fail to parse. Modern engines allow them; older ones and many tools still do not.
Why is it not folded by default?
Because changing line endings changes the file. That should be a decision you make, not one a cleaner makes for you.
