             Summary: COSString field non-ascii characters
                 Key: PDFBOX-5532
                 URL: https://issues.apache.org/jira/browse/PDFBOX-5532
             Project: PDFBox
          Issue Type: Bug
            Reporter: David


 
Hello,

I am reading a pdf document but in the COSString field non-ascii characters are being retrieved. What can be the motive? I am using version pdfbox-2.0.24.jar

This would be an example of the pdf document parsed:

COSInt\{50} 
COSInt\{0} 
PDFOperator\{Td} 
COSString\{åÅÕãÁâ@} 
PDFOperator\{Tj} 
COSFloat\{770.18} 
COSInt\{0} 
PDFOperator\{Td} 
COSString\{×–Ž–©@} 
PDFOperator\{Tj} 
COSFloat\{520.21} 
COSInt\{0}


Function java:

 public static PDDocument replaceText(PDDocument document, String searchString, String replacement) throws IOException {
		 	    
		    PDPageTree pages = document.getDocumentCatalog().getPages();
		    for (PDPage page : pages) {
		    			    	
		        PDFStreamParser parser = new PDFStreamParser(page);
		        parser.parse();
		        List tokens = parser.getTokens();
		        for (int j = 0; j < tokens.size(); j++) {
		            Object next = tokens.get(j);
		           
		            if (next instanceof Operator) {
		                Operator op = (Operator) next;
		             
		                 if (op.getName().equals("Tj")) {
		                    COSString previous = (COSString) tokens.get(j - 1);		                 
		                    String string = previous.getString();
		                    System.out.println("previous:=" + string);
		                                
		                
		                    if (string.equals(searchString)){
		                    	 COSString sx = new COSString(replacement);		
		                    	previous.setValue(sx.getBytes());
		                    	
		                    }
		                }
		            }
		        }
		        // now that the tokens are updated we will replace the page content stream.
		        PDStream updatedStream = new PDStream(document);
		        OutputStream out = updatedStream.createOutputStream();
		        ContentStreamWriter tokenWriter = new ContentStreamWriter(out);
		        tokenWriter.writeTokens(tokens);
		        page.setContents(updatedStream);
		        out.close();
		        
		        
		    }
		    return document;
		}
