What escape sequences are converted?

The Escape mode converts real LF (\n) to \\n and CRLF (\r\n) to \\r\\n. The Unescape mode reverses both conversions.

Why do JSON strings need escaped newlines?

JSON specification does not allow literal newlines inside string values. Multi-line text must use \n escape sequences instead of actual line breaks.

Does this handle Windows-style line endings?

Yes. Both LF (Unix) and CRLF (Windows) newlines are handled in Escape mode. Unescape converts both \\n and \\r\\n back to real newlines.
