When enabled, prepends an invisible zero-width signature to the output. This allows inØsight to automatically detect hidden messages across web pages, identify the base and cipher, and show the on-screen decode button.
## How ZWUS Works
1. Takes each character's Unicode code point.
2. Converts it to the chosen base (3, 6, or 8).
3. Maps each resulting digit to its assigned zero-width character from the alphabet.
4. Joins digits together; separates characters with the base's designated separator (also zero-width).
The result is a string of invisible Unicode that carries the full original text. Decoding reverses the mapping: splits on the separator, looks up each zero-width character to recover the digit, parses the base-N number back to a code point, and reconstructs the string.
For details regarding picking the optimal standard/base, see [docs/zwus.md](docs/zwus.md).
For cipher details, see [docs/cipher.md](docs/cipher.md).
## Use ZWUS in Your Own Projects
The encoder/decoder is available as a standalone package for multiple languages:
- **JavaScript/TypeScript:** [zwus on npm](https://www.npmjs.com/package/zwus)
- **Rust:** [zwus on crates.io](https://crates.io/crates/zwus)
> [!NOTE]
> Encoding works with **all Unicode characters in existence** (`U+0000` to `U+10FFFF`), including every language script, emoji, and symbol.
