Q. What can I do when passing a special character string as value (property value) and it is causing a problem?

A. There are cases where a special character string was set at value (property value) in an Automation Scenario, but the scenario fails to execute it.

A typical example is with the String Manipulation plugin. The String Manipulation plugin can take Regular Expression commands such as [+.\\]. However, there is a problem between STU and PAM when passing such a special character string because PAM reads STU's files via the Command Line Interpreter. The Command Line Interpreter has limitations with quotes, spaces, and characters like ^ and \.

To avoid these limitations, use double quotes and double backslashes. For instance,  in the case like .+\\, you must use ".+\\\\".
