Thanks for contacting support.

You may please use TextAbsorber Class in order to extract text in raw format from any PDF document. Please check following code snippet in order to do so:

TextAbsorber ta = new TextAbsorber();
ta.ExtractionOptions = new TextExtractionOptions(TextExtractionOptions.TextFormattingMode.Raw);
Document pdfDocument = new Document(dataDir + "Test (1).pdf");
pdfDocument.Pages.Accept(ta);
string text = ta.Text; // all text of PDF document

In case you still face any issue, please feel free to let us know.
