How to use the Unicode Unescape
- Paste text containing escape sequences.
- Click "Unescape Unicode" – the four-digit, brace, capital-U and hex forms are all recognised together.
- Check the notes for any unpaired surrogate, which indicates damaged data.
Frequently asked questions
Which escape formats are supported?
Four-digit sequences, ES6 brace sequences, Python eight-digit capital-U sequences and two-digit hex escapes. They can be mixed in the same input, which is common when text has passed through several systems.
What is an unpaired surrogate?
Characters above the basic plane are written as two halves. If only one half survives – because a string was truncated at the wrong point – the result is an incomplete character. The tool flags it rather than pretending the text is intact.
Does this handle HTML entities too?
No, they are a different notation. Use the HTML Entity Decoder for ampersand-style references; this tool handles backslash-style programming escapes.
