textField.setFont(new Font("Serif",Font.BOLD,12));
cannot display Korean characters only

and

textField.setFont(new Font("Monospaced",Font.BOLD,12));
cannot display English and Korean characters

The same string can display fine with "SanSerif" and "Dialog" font.

Here is the test program to reproduce this problem;

----
import java.awt.*;
import java.text.*;
import java.util.*;

class KoreanTextFieldBugTest extends Frame
{
    static String string="Actions: \uc791\uc5c5"; // Simultaneously display ISO
8859-1 and KSC5601

    public KoreanTextFieldBugTest(String fontNm)
    {
        super(fontNm);
        Button button = new Button(string);
        TextField textField = new TextField(20);
        textField.setFont(new Font(fontNm,Font.BOLD,12));

        setLayout(new BorderLayout());
        add("South",button);
        add("North",textField);
        textField.setText(string);
        pack();
    }

    public static void main(String[] args)
    {
        KoreanTextFieldBugTest koreanTextFieldBugTestMonospaced = new KoreanText
FieldBugTest("Monospaced");
        koreanTextFieldBugTestMonospaced.show();
        KoreanTextFieldBugTest koreanTextFieldBugTestSansSerif = new KoreanTextF
ieldBugTest("SansSerif");
        koreanTextFieldBugTestSansSerif.show();
        KoreanTextFieldBugTest koreanTextFieldBugTestSerif = new KoreanTextField
BugTest("Serif");
        koreanTextFieldBugTestSerif.show();
        KoreanTextFieldBugTest koreanTextFieldBugTestDialog = new KoreanTextFiel
dBugTest("Dialog");
        koreanTextFieldBugTestDialog.show();
    }
}
