Aspose.Words FormField text contains double-quotes

When iterating through the FormFields collection, we are having a problem when the FormField.Result contains double-quote characters ("). When iterating to the field with the double quotes, we get the following Aspose.Words error:

FormField.Result 'field.Result' threw an exception of type 'System.NullReferenceException' string {System.NullReferenceException}
System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object.

What is the best way to deal with double-quotes in form fields?

Hello!
Thank you for your interest in Aspose.Words.
Iā€™m trying to reproduce this but MS Word seemingly escapes the double quote characters in form fields. FormField.Result property is invoked without issues but it gives ā€œ111ā€. (I paste as is, without extra quotes.) Here is my code and the document is attached.

private static void TestFormFieldsWithQuotes()
{
    string fileName = "ff_double_quotes.doc";
    Document doc = new Document(fileName);
    NodeCollection formFields = doc.GetChildNodes(NodeType.FormField, true, false);
    foreach (FormField ff in formFields)
    {
        string result = ff.Result;
    }
}

Please provide your document for testing or explain how it can be created programmatically. Also please show the code snippet that reproduces this issue.
Regards,
