WATERMARK SLAYER

Remove hidden characters from text

Invisible Unicode characters can arrive through copy-paste, editors, layout systems, or intentional language shaping. Watermark Slayer removes supported low-risk marks and keeps risky cases reviewable.

Why not delete every invisible character

Zero-width joiners, non-joiners, bidirectional controls, variation selectors, and word joiners can be meaningful in languages, emoji, typography, or interchange. Blanket deletion can corrupt text.

  • Supported cleanup remains explicit
  • Risky controls stay report-only
  • Review changes shows what was altered

Hidden does not mean malicious

The presence of a format control is an observation, not an authorship verdict. Legitimate software and writing systems use many of the same code points.
