# 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.

## FAQ

### 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.
