PDFCopy WILL copy hidden text - it copies everything...
Your method will copying everything AND any hidden text will stay
hidden. Are you saying that it does not??
The only way to remove hidden text would be for you to parse the
content stream (PdfContentByte) yourself and manipulate it to remove
the things you don't want. NOT trivial - but well defined.
