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;
}
