# __unescape

*Also documented in context in the [full Functions and Variables reference](/user-manual/functions/#__unescape).*

The unescape function returns the result of evaluating a Java-escaped string. See also `__char()` above.

This allows one to add characters to fields which are otherwise tricky (or impossible) to define via the GUI.

| Name | Required | Description |
| --- | --- | --- |
| String to unescape | Yes | The string to be unescaped. |

Examples:

`\${__unescape(\r\n)}` = `CRLF`

`\${__unescape(1\t2)}` = `1`[tab]`2`
