encoding issue after pdfbox

I want to extract text in PDF on Java, so I use pdfbox library. PDF file seems to have been written by hwp(korea word edit software) before it was converted to a PDF file.
This is my simple API.
#RestController
#RequiredArgsConstructor
public class QuestionController {
private final QuestionParseService questionParseService;
#GetMapping("/")
public ResponseEntity<?> parsePDF() throws IOException {
return ResponseEntity.ok(questionParseService.parsePDF());
}
}
#Service
public class QuestionParseService {
public String parsePDF() throws IOException {
File file = new File("filePath");
PDDocument document = PDDocument.load(file);
PDFTextStripper s = new PDFTextStripper();
String content = s.getText(document);
return content;
}
}
This is my PDF file PDF file
But, the API result of question 1 was

How can I get correctly encoded text?

Not able to create package using docx4j WordprocessingMLPackage in java

Converting a html file or string through docx4j getting an error while running the code
public static void convertHtmltoWord2(String html) {
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.createPackage();
NumberingDefinitionsPart ndp = new NumberingDefinitionsPart();
wordMLPackage.getMainDocumentPart().addTargetPart(ndp);
ndp.unmarshalDefaultNumbering();
// Convert the HTML, and add it into the empty docx we made
XHTMLImporterImpl XHTMLImporter = new XHTMLImporterImpl(wordMLPackage);
XHTMLImporter.setHyperlinkStyle("Hyperlink");
wordMLPackage.getMainDocumentPart().getContent().addAll(
XHTMLImporter.convert(html, baseURL) );
wordMLPackage.save(new java.io.File("C:\\Converted_Word.docx") );
}
Below Error:
java.util.NoSuchElementException
at org.docx4j.openpackaging.parts.WordprocessingML.MainDocumentPart.<init>(MainDocumentPart.java:76)
at org.docx4j.openpackaging.packages.WordprocessingMLPackage.createPackage(WordprocessingMLPackage.java:432)

Any idea why its not working?

PdfBox flatten pdf template fields but pdf is still editable

I have a pdf template and with the following code I open it, edit, and then save it with another name after flattening it. But when I open the new pdf file, the fields are still editable.
public static void main(String[] args) throws IOException {
PDDocument doc = PDDocument.load(new File("template.pdf"));
PDDocumentCatalog docCatalog = doc.getDocumentCatalog();
PDAcroForm acroForm = docCatalog.getAcroForm();
for ( PDField field : acroForm.getFields()) {
if (field.getFieldType().equals("Tx")) {
field.setValue(field.getPartialName());
}
System.out.println(field.getFieldType());
}
acroForm.flatten();
doc.save("finalFile.pdf");
doc.close();
}
I read other questions about flattening but no one has my problem.
Am I missing anything?
I'm on PDFBox 2.0.12

PDF parser text contains

I want to verify PDF Document using TestNG and PDFBox.
I would ask, is PDF able to check contains text like this:
PDFParser parser = new PDFParser(stream);
parser.getDocument().conntains("ABC")

Try below code:-
public void ReadPDF() throws Exception {
URL TestURL = new URL("http://www.axmag.com/download/pdfurl-guide.pdf");
BufferedInputStream TestFile = new BufferedInputStream(TestURL.openStream());
PDFParser TestPDF = new PDFParser(TestFile);
TestPDF.parse();
String TestText = new PDFTextStripper().getText(TestPDF.getPDDocument());
Assert.assertTrue(TestText.contains("Open the setting.xml, you can see it is like this"));
}

InputSource not working in Android while retrieving data from Assets?

After checking the answers from the other questions and applying them to my program, I still have problems loading assets from my Project.
Here is the block of code which has the problem and it seems to not go past the line with the comment //BUG
public void parseXmlFile(String xml_file, String object, String xml_class, String pointer, Activity activity, TextView test) throws ParserConfigurationException, SAXException, IOException{
view = test;
view.setText("2.1");
categories_list = new ArrayList<Category>();
//instantiate String object sto be used throughout class
object_name = object;
class_type = xml_class;
value_pointer = pointer;
//get factory
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
//get instance of document builder to build document from xml file
DocumentBuilder builder = factory.newDocumentBuilder();
//Create bytestream which allows a stream of data from xml to document builder
ByteArrayInputStream byte_stream = new ByteArrayInputStream(xml_file.getBytes("utf-8"));
//create an input source for the bytestream
InputSource input_src = new InputSource(activity.getAssets().open(xml_file));
dom = builder.parse(input_src); //BUG
parseDocument();
byte_stream.close();
}
My XML is in the assets folder and the app doesn't crash, it just doesn't do anything. The response i'm supposed to get is a listview of buttons gotten from the parsing of the XML. The algorithm to parse the XML works as it has been tested in a normal Java application. I just want to apply it to the Android app.
If you want more info just comment.
