How to use Unicode Encoder

Type your text, and the tool encodes it into \u escape-sequence Unicode code points.

Frequently asked questions

What is a Unicode escape sequence?

A \u followed by a 4-digit hex code point, like \u0041 for 'A'. Used in JavaScript, JSON, Java, C.

What is the difference between \u and \U?

\u is for 4-digit BMP code points. \U (Python) handles full range including emoji above U+FFFF.

Should I encode ASCII characters?

Only encode non-ASCII characters for safety. Encoding ASCII is valid but unnecessary.
