Invisible AI Chart Detector

Detects & cleans invisible AI-style watermark characters in text:

• Unicode Cf (format controls): ZWSP/ZWNJ/ZWJ/WJ, LRM/RLM/ALM, BOM, bidi controls (LRE/RLE/LRO/RLO/PDF/isolates), etc.
• (Optional) Special spaces: NBSP/NNBSP/Ideographic/En/Em/Thin/Hair/MMSP.

Commands

• Toggle Visualize (Replace ↔ Restore) — invisibleAiChartDetector.toggleVisualize
  Replaces watermark chars with ⟦U+XXXX⟧ so you can see & search them; run again to restore.
• Remove All Watermarks — invisibleAiChartDetector.removeAll
• Scan & Report (Output) — invisibleAiChartDetector.scanReport
• Clean In Place — invisibleAiChartDetector.cleanInPlace
  Space-like watermarks → ASCII space; others removed.
• Clean & Save Copy… — invisibleAiChartDetector.cleanSaveCopy

Settings

• watermark.includeUnicodeCf (default true)
• watermark.includeSpaceFamily (default true)
• detect.includeNewlines (default false)
• replace.format (default unicode) — shown as ⟦U+XXXX⟧ for safe restore
• replace.includeNewlines (default false)
• remove.includeNewlines (default false)
• clean.replaceSpaceLikesToAscii (default true)
• eolBadge (default false)
• doubleBlankThreshold (default 2)

Notes

ASCII space (U+0020), TAB (U+0009), and newlines are not treated as watermarks unless explicitly enabled.
