This tool is an online utility for mutual conversion between Unicode and Chinese, supporting JavaScript-style \uXXXX escape sequences and HTML entity forms of decimal and hexadecimal encoding, helping developers quickly encode or decode Chinese content.

What is Unicode?

Unicode is a character encoding standard used on computers, designed to provide a unique numeric code for every character in the world. The Unicode code point for the Chinese character "中" is U+4E2D, with common representations such as: \u4e2d (JS escape), 中 (decimal entity), 中 (hexadecimal entity).

Supported Formats

• \uXXXX — Escape format commonly used in JavaScript, Java, Python, and other languages (fixed 4 hexadecimal digits per character).
• &#XXXX; — HTML entity format using decimal numbers to represent character encoding, commonly used to display special characters in web pages.
• &#xXXXX; — HTML entity format using hexadecimal numbers to represent character encoding.

Main Use Cases

• Process Unicode-encoded data returned by APIs and restore it to readable Chinese content.
• Convert to Unicode to avoid character encoding issues when hardcoding Chinese content in code.
• Parse web page source code containing HTML entity encoding to view the actual characters.
• Troubleshoot garbled text issues and verify the actual Unicode code points of characters.

Tool Features

• Bidirectional conversion: Supports Unicode to Chinese and Chinese to Unicode with one click.
• Multi-format support: Compatible with \uXXXX, &#XXXX;, and &#xXXXX; three mainstream encoding formats.
• Two-column layout: Input and output are displayed separately, making it more intuitive to compare content before and after conversion.
• Mixed processing: Can process text with mixed Chinese, English, and symbols, encoding only non-ASCII characters.
• Line number editor: Both left and right text boxes have line numbers, making it easy to view and locate multi-line content.
• Safe and reliable: Pure front-end execution, no data uploaded, absolutely protects your data privacy.
