Unicode Encoder/Decoder

Introduction​

Unicode Encoder/Decoder is a simple and practical online tool for converting between plain text (like English, Chinese, Emoji) and Unicode encoding.

Key Features​

  • Bidirectional Conversion: Supports encoding text to Unicode and decoding Unicode to text.
  • Multi-format Support:
    • \uXXXX: Common JavaScript/Java/C++ format (e.g., \u0048\u0065\u006C\u006C\u006F)
    • &#xXXXX;: HTML Hexadecimal Entity format (e.g., Hello)
    • &#XXXX;: HTML Decimal Entity format (e.g., Hello)
  • Real-time Processing: Results appear instantly as you type.
  • Privacy First: All conversion logic executes locally in your browser. No data is uploaded to any server.

Use Cases​

  1. Frontend Development: Using special characters in JS or CSS requires conversion to \uXXXX format.
  2. Backend Development: Handling encoding issues or internationalization (i18n) configurations.
  3. HTML Editing: Inserting special symbols in web pages or avoiding character conflicts.
  4. Data Cleaning: Restoring text from logs or databases containing Unicode escape sequences.
