🌐 What is Unicode Converter?
Unicode is an international standard that represents all characters worldwide in a single character set. Each character is assigned a unique code point (U+XXXX), supporting over 150,000 characters. This tool converts text to Unicode escape (\uXXXX) format or UTF-8 bytes (HEX). It is useful for safely representing non-ASCII characters in JSON and JavaScript source code.
📋 Conversion Modes
Text → Unicode (\uXXXX)
Converts each character to \u + 4-digit hex. Used in JavaScript and JSON. Example: "A" → \u0041
Text → UTF-8 (HEX)
Shows UTF-8 encoded byte values in hexadecimal. Useful for network debugging. Example: "A" → 41
Frequently Asked Questions
What is the difference between Unicode and UTF-8?▼
Unicode is a character set (which number is assigned to each character), while UTF-8 is an encoding method (how to store those numbers as bytes). UTF-8 is the most widely used way to store Unicode.
Where is the \uXXXX format used?▼
It is used in JavaScript strings and JSON files to represent non-ASCII characters. The \u prefix followed by 4 hex digits can represent all BMP (Basic Multilingual Plane) characters.
How many bytes is a CJK character in UTF-8?▼
CJK characters (Chinese, Japanese, Korean) use 3 bytes in UTF-8 encoding, 2 bytes in UTF-16. Their Unicode code points typically fall in various ranges like U+4E00-U+9FFF.
