Why it may appear legitimately

It can occur as a decoded byte-order marker or a historical no-break marker, and it can lead a C2PA unstructured-text wrapper.

  • Decoded text and copied rich text

Launch behavior

Registry status: supported. Watermark Slayer can propose a reviewable removal edit only when the writer explicitly selects this supported cleanup.

What a change could affect

Changing the marker can alter no-break behavior or damage credential-like C2PA framing.

  • A marker beginning a recognized C2PA text wrapper is never removable.

Claim boundary

Finding this artifact says only that the specified code point or framing was observed. It is not an authorship verdict, detector score, or evidence that text came from a particular system.
