Understanding Unicode

Unicode is a universal character encoding standard that assigns a unique number (Code Point) to every character across all languages and writing systems in the world. Unlike older encodings (like ASCII), Unicode can represent emojis, mathematical symbols, and ancient scripts simultaneously.

This tool helps developers visualize these code points and convert text into formats compatible with various programming languages (JavaScript, Java, Python) and web technologies (HTML).

What is a Code Point?

A code point is a unique integer assigned to a character. For example, the capital letter 'A' is assigned U+0041. The Earth emoji 🌍 is assigned U+1F30D.

Conversion Modes

Unicode Escape Sequence (\uXXXX)

Commonly used in Java, JavaScript, and JSON strings. This converts non-ASCII characters into a format starting with `\u` followed by 4 hexadecimal digits (or `\u{...}` for extended characters).

Example: "café" becomes "caf\u00e9".

HTML Entities (&#...;)

Used in HTML source code to display characters that might otherwise be interpreted as HTML tags. It uses the decimal or hexadecimal code point inside `&#` and `;`.

Example: © becomes ©.
