Where it comes from

Legacy Hebrew and Arabic document workflows, and text copied out of them.

Why it matters

Like its left-to-right twin it nests, leaks past the end of the intended span when unterminated, and is completely invisible while doing it.

Before and after

BeforeU+202Bשלום‬
Afterשלום

The Hebrew word reads right to left on its own. The embedding around it adds nothing but risk.

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

Superseded by U+2067 RIGHT-TO-LEFT ISOLATE, which cannot leak. Genuine Hebrew and Arabic prose needs no embedding at all — the bidi algorithm reads the direction from the letters.

How to remove it

The default pass removes it, unconditionally.

Is it an AI watermark?

Not a watermark

No. A legacy layout control from bidi-aware editors. Nothing to do with generated text.

No connection to machine-generated text. It comes from software, from a keyboard, or from a person.

Questions

Will removing it break my Hebrew?

No. Hebrew and Arabic letters carry their own directionality, so the bidi algorithm lays them out correctly with no control characters present.

What about the marks next to the text?

U+200E and U+200F are treated differently: next to right-to-left text they are kept, because there they resolve genuine ambiguity.
