What is Unicode Encoding?

Unicode encoding converts each character in your text into its corresponding Unicode escape sequence — a \u prefix followed by a four-digit hexadecimal code point. For example, the letter A becomes \u0041, and the Korean character 가 becomes \uAC00.

Every character in the Unicode Standard has a unique code point, covering over 140,000 characters across 150+ scripts — from Latin and Korean to Arabic, Chinese, emoji, and mathematical symbols.

When to Use Unicode Encoding

• Source code: Embedding non-ASCII characters in Java, JavaScript, Python, or C# string literals where only ASCII is safe.
• JSON & XML: Ensuring special or non-Latin characters are safely represented in data formats.
• Regex patterns: Writing portable regular expressions using Unicode code points instead of raw characters.
• Debugging: Inspecting what code point corresponds to an unexpected character in a string.

Example

Input text:

Hello, 세계!

Unicode encoded output:

\u0048\u0065\u006C\u006C\u006F\u002C\u0020\uC138\uACC4\u0021
