A DESCRIPTION OF THE PROBLEM :
Font.canDisplay(int) and Font.canDisplayUpTo do not work correctly with variation selectors.

Install some Japanese fonts for all users and run the test code.


---------- BEGIN SOURCE ----------
public static void main(String[] args) {
    int cp[] = { 0x8FBB, 0xE0101 };

    String str = new String(cp, 0, cp.length);
    System.out.println(str);

    Font font = new Font(fontName, Font.PLAIN, 12);

    System.out.println(font.canDisplayUpTo(str) == -1); // => false
    System.out.println(font.canDisplay(cp[0])); // => true
    System.out.println(font1.canDisplay(cp[1])); // => false
