Unicode Encoder/Decoder

📖 Description

1. Why is Unicode Conversion Needed?

In cross-platform development and web processing, different representations of Unicode are crucial:

• JavaScript/Java Development: To prevent encoding errors caused by non-ASCII characters in source code, hexadecimal escape formats like \u4f60\u597d are commonly used.
• HTML/XML Display: To display special symbols in environments that do not support UTF-8, they need to be escaped into HTML entities (e.g., 你).
• Eliminate Garbled Text: When you receive garbled text starting with something like \u, this tool can restore it to readable native language text with one click.
• CSS Stylesheets: Hexadecimal Unicode code points are often required in the CSS content property.

2. Core Features Explained

This site's tool integrates various mainstream Unicode escape formats to meet the needs of different scenarios:

A. \u Format (JavaScript/Java/Python)

• Encode: Convert text into a hexadecimal sequence starting with \u (e.g., \u4f60).
• Application: Suitable for JS strings, JSON configuration files, and various backend source code.

B. &# Format (HTML/XML Entities)

• Decimal: Convert characters into standard HTML entity format (e.g., 你).
• Hexadecimal: Convert to hexadecimal entities compatible with CSS or HTML (e.g., 你).

C. Unicode Code Point Extraction

• Display the original code point of a character in the Unicode standard (e.g., U+4F60), making it easy to look up Unicode character tables.

D. Absolute Privacy Guarantee: Local Processing

• Zero Upload: All character conversion logic is performed in real-time locally in your browser.
• Security: Your sensitive text (such as private messages, code snippets) is never sent to the server. Processing speed depends solely on your computer's performance, with 100% privacy control.
