File Conversion Tools
Escape special characters and text strings into Unicode escape sequences (e.g. \uXXXX) or HTML entities.
Follow these simple steps to get instant, accurate results directly in your browser:
Type or paste text, symbols, or emojis into the input bar.
Choose your desired format: Standard Code Point (U+XXXX), JS/JSON (\uXXXX), HTML entity, or CSS escape.
Copy the encoded escape sequence directly into your source code.
The Unicode Encode tool converts text characters, symbols, and emojis into standardized Unicode code points (such as U+0041 for 'A') and escape sequences for JavaScript (\u0041), Python (\u0041 / \U00000041), HTML entities (A / A), and CSS (\0041).
Unicode is the universal character encoding standard that assigns a unique numeric code point to every character, symbol, and emoji across world languages. Encoding characters into escape sequences prevents encoding corruption when source files are transferred across legacy systems or non-UTF-8 compilers.
All encoding calculations run in client-side memory, allowing developers to inspect character code points and encoding formats securely.
Accurately handles surrogate pairs for high-plane Unicode characters and emojis.
Generates escape codes for JavaScript, Python, C++, HTML, and CSS.
Displays the official Unicode character name, category, and block plane.
Encodes characters locally on your device with zero data transmission.
Escape international symbols in JavaScript and JSON to avoid UTF-8 file encoding errors.
Generate CSS-escaped Unicode characters (e.g. \2713 for checkmark) for content: '...' properties.
Generate safe decimal and hexadecimal HTML character entities for email templates.
