Why Unicode Escaping Matters
File Encoding
Some systems require ASCII-only text. Unicode escape allows safe storage of international characters.
JavaScript Strings
JavaScript source code often uses Unicode escape sequences for special characters.
JSON Data
JSON encoding uses Unicode escapes for non-ASCII characters in strings.
Compatibility
Ensure text is compatible with systems that don't support UTF-8 encoding.

Emoji Support
Fully supports emojis, special symbols, and all Unicode characters including surrogates.
Bidirectional
Both escape and unescape operations work flawlessly. Fully reversible conversion.
International Text
Handle Chinese, Arabic, Cyrillic, Hebrew, and all world languages correctly.
Privacy First
100% client-side processing. No server communication, your data stays private.
Frequently Asked Questions
What is Unicode escape?
Unicode escape sequences represent characters using their Unicode code point in hexadecimal format, typically written as \uXXXX or \uXXXXXX.
Why would I escape Unicode?
Unicode escaping is useful when you need to store or transmit text in ASCII-only systems, or when working with programming languages that require escape sequences.
Does this handle emojis?
Yes, emojis are fully supported. Complex emojis with modifiers and skin tones are correctly escaped and unescaped.
What's the difference between \uXXXX and \uXXXXXX?
\uXXXX is the legacy format limited to 4 hex digits. \uXXXXXX is the modern format supporting the full Unicode range.
Can I escape ASCII characters?
This tool automatically escapes only non-ASCII characters. ASCII letters stay as-is for readability. You can manually edit if needed.
Is my data secure?
Yes, all processing happens in your browser. Your data is never sent to any server and is completely private.
About Unicode Escaping
Unicode escaping is a fundamental technique for safely representing international characters in systems that don't natively support UTF-8 or full Unicode.
Common Uses:
- JavaScript Code: String literals containing Unicode characters
- JSON Encoding: Non-ASCII characters in JSON strings
- HTML Entities: Alternative to HTML character entities
- Configuration Files: System configuration needing ASCII-only format
- Legacy Systems: Systems that don't support UTF-8 encoding
- Code Comments: International text in code comments
