class Unicodechar{
    public static void main(String[] args){

                //declare a character initialized to Ethiopic
        char fidel='\u1200';
        // print Ethiopic Unicode (version 3.0)
                  while(fidel<='\u137C'){
            for(int i=0;i<8;i++){
                System.out.println((int)fidel +", ");
                fidel++;
            }
