Japanese

I'm intrigued to discover what I' not doing right with this piece of code :

Font font = new Font("x-JIS0208"/*"Cp930"*/, Font.PLAIN, 12);
    
    String sti = new String("We would like this to appear in Japanese");
    
    
    jta.setFont(font);
    
    
    Locale loc = new Locale("ja","JP");
    Locale.setDefault(loc);
    
    
    StringCharacterIterator sci = new StringCharacterIterator((loc.getDisplayLanguage()).toString());
    
    while(!(sci.current() == sci.DONE)){jta.append(new String()+sci.current());sci.next();}
    
    
    sci.setText(sti);
    while(!(sci.current()==sci.DONE)){jta.append(new String()+sci.current());sci.next();}

 ... that the JTextArea (jta) displays Japanese characters for the display language, but doesn't render the 'sti' String in terms of the same characters. Having never been on this ground before, I'm stumped. ;)
