Which formats are supported?

JSON (string escaping), JavaScript (quotes, backticks, control chars), HTML entities (named and numeric), SQL (single-quote doubling), and C-style backslash escapes including \\xNN and \\uNNNN.

Why does unescaping sometimes show an error?

If the input contains an invalid escape sequence — for example a dangling backslash or a malformed \\u code — the parser reports it instead of producing a wrong result.
