why '?' appears as output while Printing unicode characters in java

While printing certain unicode characters in java we get output as '?'. Why is it so and is there any way to print these characters?

This is my code

String symbol1="u200d";
        StringBuilder strg = new StringBuilder("unicodecharacter");
        strg.insert(5,symbol1);
        System.out.println("After insertion...");
        System.out.println(strg.toString());

Output is After insertion... unico?decharacter
