如何在韩语韩语中显示​​E384B1等？

Question

我有一个简单的ReadWriteUnicode类，它使用drawString在Frame中显示unicode值。我使用\ u65e5 \ u672和MONOSPACED字体测试它并获得中文。当我传递\ ue384b1 \ ue384b2等字体名称Hangul时，我得到[] b1 [] b2，其中[]是一个方框。

如何获得汉字韩语的三字节代码？

public class ReadWriteUnicodeExample {

    static void writeOutput(String str) {
        try {
            FileOutputStream fos = new FileOutputStream("test.txt");
            Writer out = new OutputStreamWriter(fos, "UTF8");
            out.write(str);
            out.close();
        } 
        catch (IOException e) {
            e.printStackTrace();
        }
    }

    static String readInput() {
        StringBuffer buffer = new StringBuffer();
        try {
            FileInputStream fis = new FileInputStream("test.txt");
            InputStreamReader isr = new InputStreamReader(fis, "UTF8");
            Reader in = new BufferedReader(isr);
            int ch;
            while ((ch = in.read()) > -1) {
                buffer.append((char)ch);
            }
            in.close();
            return buffer.toString();
        } 
        catch (IOException e) {
            e.printStackTrace();
            return null;
        }
    }

    public static void main(String[] args) {
        String jaString = new String("\u65e5\u672c\u8a9e\u6587\u5b57\u5217");
        writeOutput(jaString); 
        String inputString = readInput();
        String displayString = jaString + " " + inputString;
        new ShowString(displayString, "Conversion Demo", "MONOSPACED");
        String koreanStr = new String ("\ue384b1\ue384b2\ue384b4\ue384b7\ue384b8\ue384b9");
        writeOutput(koreanStr); 
        inputString = readInput();
        displayString = koreanStr + " " + inputString;
        new ShowString(displayString, "Conversion Demo", "Hangul");
    }
}

class ShowString extends Frame {

    FontMetrics fontM;
    String outString;

    ShowString (String target, String title, String fontName) {

        setTitle(title);
        outString = target;

        Font font = new Font(fontName, Font.PLAIN, 36);
        fontM = getFontMetrics(font);
        setFont(font);

        int size = 0;
        for (int i = 0; i < outString.length(); i++) {
           size += fontM.charWidth(outString.charAt(i));
        }
        size += 24;

        setSize(size, fontM.getHeight() + 60);
        setLocation(getSize().width/2, getSize().height/2);
        setVisible(true);
    }

    public void paint(Graphics g) {
        Insets insets = getInsets();
        int x = insets.left; 
        int y = insets.top;
        g.drawString(outString, x + 6, y + fontM.getAscent() + 14);
    }
}
