Unicode Encode

Convert text to Unicode escape sequences (\uXXXX format).

Unicode encoding converts each character in your text to its corresponding Unicode escape sequence in the format \uXXXX, where XXXX is the four-digit hexadecimal code point. This representation is widely used in JavaScript string literals, JSON, Java source code, and other programming contexts where non-ASCII characters need to be safely embedded as ASCII-only escape sequences.

FAQ

What is a Unicode escape sequence?
A Unicode escape sequence represents a character as \uXXXX where XXXX is the four-digit hexadecimal code point (U+0000 to U+FFFF). For example, the letter A is \u0041, the copyright symbol is \u00A9, and the Greek letter alpha is \u03B1.
How are characters outside the Basic Multilingual Plane handled?
Characters with code points above U+FFFF (such as emoji) require two surrogate pairs in JavaScript's UTF-16 encoding. For example, 😀 (U+1F600) encodes as \uD83D\uDE00. This tool outputs the surrogate pair representation compatible with JavaScript strings.
Where would I use Unicode escape sequences?
Unicode escapes are useful in JavaScript and Java source files when you need to embed non-ASCII characters but want the source file to remain ASCII-only. They are also used in JSON strings, configuration files, and any context where non-ASCII characters might cause encoding issues.
