A demo application and utility library that invisibly encodes usernames into text using zero-width Unicode characters, and decodes them back. It demonstrates how copied text can be fingerprinted to identify the user who leaked it.

Use cases

• detect hidden zero-width characters in copied text
• fingerprint text with a username before sharing it
• trace the source of leaked text snippets
• learn about zero-width character steganography
• encode and decode invisible watermarks in text

When to choose

• you want to watermark text invisibly to identify leakers
• you need to check whether text contains hidden zero-width characters
• you want an interactive demo of this technique

When to avoid

• you need robust production-grade text watermarking with error tolerance
• you need watermarking that survives copy-paste normalization or reformatting
• you need a supported library with a license and active maintenance guarantees
