Invisible Ai Character De

Spot and remove invisible Unicode watermarks (ZWSP/ZWNJ/ZWJ, BOM, bidi controls), special spaces (NBSP, thin/hair/en/em), variation selectors, and common confusables (smart quotes, long dashes, ellipsis, minus) on any page. Visualize targets inline (reversible), normalize in place, or clean via right-click ‘Invisible AI: Clean page’. All processing is local; nothing is sent off-page.

Features:
- Visualize targets as ⟦U+XXXX⟧ and restore safely.
- Clean in place: replace when safe (e.g., NBSP→space, smart quotes→ASCII) or remove invisibles.
- Options for Unicode Cf, special spaces, variation selectors, confusables, and newlines.
- Context menu action to clean without opening the popup.
- Privacy-friendly: no telemetry, no network calls, runs entirely in the page context.
