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.
