Why remove hidden watermark characters?

Generative AI platforms frequently insert zero-width characters and directional controls to trace copied output. Leaving them untouched can trigger spam filters, legal review flags, or unusual formatting in downstream editors.

This remover surfaces every hidden mark, labels it with its Unicode range, and lets you ship a clean, attribution-free draft.
