Unicode Escape Converter

Convert characters to \u escape sequences and back — for JSON, JavaScript and source code.

To escape Unicode characters, paste text and every non-ASCII character becomes a numeric escape sequence. Choose the style your language expects — \u00e9 for JavaScript and JSON, \u{1f389} for ES6, \0000e9 for CSS, or numeric HTML entities.

Frequently asked questions

Why do some characters need two escapes?

Because \u only addresses the first 65,536 code points. Anything above that — most emoji and many rarer scripts — needs a surrogate pair of two \u escapes, or the newer \u{...} form which takes the code point directly.
