An SSCCE helps a lot!  I was wrong about the -1 to length(), it should 
just be length().  The following seems to work for me.  If you have some 
different idea, please write a code example so we can tell what you mean.



package quicktest;

import javax.swing.JFrame;
import javax.swing.JTextArea;
import javax.swing.SwingUtilities;

/**
  *
  * @author Brenden
  */
public class Cjk {

    public static void main(String[] args) {
       SwingUtilities.invokeLater(new Runnable() {

          public void run() {
             createGui();
          }
       });
    }

    private static void createGui() {
       JFrame frame = new JFrame();

       int[] korChars = new int[10];
       for (int i = 0; i < korChars.length; i++) {
          korChars[i] = 0xAC00+i;
       }
       String kor = "test: "+new String( korChars, 0, korChars.length );
       JTextArea ta = new JTextArea( kor );
       frame.add(ta);

       ta.append("\nCount: "+ kor.codePointCount(0, kor.length() ));

       frame.pack();
       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
       frame.setLocationRelativeTo(null);
       frame.setVisible(true);
    }
}
