Hi Mike, Thanks very much, I tested and result is the same, from source code it seems that suppressDuplicateOverlappingText parameter does not have effect if I call PDFTextStripper.getText(..) directly. I will check more to see if I can use method processEncodedText(..).
Which version of PDFBox did you use (Tika has not used PDFBox 1.5 yet)?
