Unicode Escape

Escape non-ASCII characters as \uXXXX sequences entirely in your browser.

How it works

  1. Paste text, or open a file.
  2. Click Escape.
  3. Copy or download the result — non-ASCII characters become \uXXXX sequences.

Frequently asked questions

Is my text sent anywhere?
No. Escaping happens entirely on your device.
Which characters are escaped?
Any character outside the printable ASCII range (code point above 127). Plain ASCII text is left untouched.
What happens to characters outside the Basic Multilingual Plane, like emoji?
They're represented as a surrogate pair — two \uXXXX sequences — the same way JavaScript string literals encode them internally.
