Frequently Asked Questions

What is the Unicode Converter?

The Unicode Converter is an online tool that escapes special characters to \uXXXX format and unescapes them back to readable text. It runs entirely in your browser with no data sent to any server.

What formats does it support?

The Unicode Converter supports \uXXXX escape sequences. It can escape non-ASCII characters to Unicode escape format and unescape them back to readable text.

What is the \uXXXX escape format?

The \uXXXX format represents a Unicode character using 4 hexadecimal digits. For example, \u0041 represents the letter A. This format is commonly used in JavaScript strings, JSON files, and other programming contexts to encode non-ASCII characters safely.

Does it handle surrogate pairs for characters beyond the BMP?

Yes. Characters outside the Basic Multilingual Plane (code points above U+FFFF) are encoded as surrogate pairs using two \uXXXX sequences. For example, emoji characters like 😀 (U+1F600) become \uD83D\uDE00 in escaped form.

Can I convert in both directions?

Yes. The tool supports both Escape mode (text to \uXXXX) and Unescape mode (\uXXXX back to text). You can switch between modes instantly using the toggle, making it easy to convert in either direction.
