What problem does it solve?

This Skill enables hiding arbitrary UTF-8 text inside a visible marker by encoding bytes as Unicode Variation Selectors, allowing covert data embedding in plain text.

Core Features & Use Cases

  • Encode and decode text by mapping UTF-8 bytes to Variation Selectors (U+FE00-U+FE0F and U+E0100-U+E01EF)
  • Any Unicode character can serve as a marker (emojis, letters, numbers, symbols)
  • Self-contained with zero external dependencies (TypeScript/JavaScript)
  • Simple integration via a React hook and optional UI components for encoding/decoding

Quick Start

Use the emoji-encoder to encode a message with a chosen marker, then paste the encoded result into another document to decode.
