java Extracting Text from a korean RTF

Question

Extracting text from a EULA file to display to a user using jsp. The text that is in the RTF file is along the lines of:

적용 범위. 본 최종 

However when I extract and print the text to the console I end up with a different format like so:

Àû¿ë ¹üÀ§. º» ÃÖ

I believe it has to do with the encoding, but files that contain English, Spanish, and Russian characters work fine. Why is it displaying these odd characters, and how to i get the expected output?

private static String rtfToHtml(Reader rtf, String contentType) throws IOException
    {
        final JEditorPane p = new JEditorPane();
        p.setContentType("text/rtf");
        EditorKit kitRtf = p.getEditorKitForContentType("text/rtf");
        try
        {
            kitRtf.read(rtf, p.getDocument(), 0);
            kitRtf = null;
            final EditorKit kitHtml = p.getEditorKitForContentType(contentType);
            final Writer writer = new StringWriter();
            //          writer.write("Content-Type: text/plain; charset=utf-8\n\n");
            kitHtml.write(writer, p.getDocument(), 0, p.getDocument().getLength());
            // Utf-8 encoding the string 

            return writer.toString();
        }
        catch (final BadLocationException e)
        {
            e.printStackTrace();
        }
        return null;
    }

public static String extractEulaToPlain(String eulaDocumentLocation) throws FileNotFoundException, IOException
    {
        final FileInputStream is = new FileInputStream(eulaDocumentLocation);
        final InputStreamReader isr = new InputStreamReader(is, "UTF-8");
        final BufferedReader buffReader = new BufferedReader(isr);

        final String plain = rtfToHtml(buffReader, "text/plain");

EDIT: (sample rtf file)

I used RTF Parser Kit to perform the conversion. Here's the converted text from your sample RTF file:

1.적용 범위. 본 최종 사용자 라이센스 계약(이하 "계약")은 동봉된 소프트웨어의 사용에 적용되며, 귀하와및 자회사(총칭간에 체결된 별도 계약의 구속을 받는 경우는 제외됩니다. 귀하가 소프트웨어를 다운로드하거나, 복사하거나, 사용하는 경우 본 계약에 동의하는 것으로 간주됩니다. HPE는 본 계약을 영어 이외의 특정 언어로 번역하여 다음 위치에서 제공합니다

That certainly looks more promising than the output you were getting!

You can use RTF Parser Kit working with streams:

new StreamTextConverter().convert(new RtfStreamSource(inputStream), outputStream, "UTF-8");

or as a convenience there is a converter provided which provides the output as a string:

StringTextConverter converter = new StringTextConverter();
converter.convert(new RtfStreamSource(inputStream));
String extractedText = converter.getText();
