懒人查看当前字节编码的方法（用在JAVA里面的）

byte[]   bt1=right.getBytes("iso8859-1");  
                byte[]   bt2=right.getBytes("gb2312");  
                byte[]   bt3=right.getBytes("utf-8");  
                byte[]   bt4=right.getBytes("unicode");  
                System.out.println(bt1);  
                System.out.println(bt2);  
                System.out.println(bt3);  
                System.out.println(bt4);  
                System.out.println(new   String(bt1,"utf-8"));  
                System.out.println(new   String(bt2,"utf-8"));  
                System.out.println(new   String(bt3,"utf-8"));  
                System.out.println(new   String(bt4,"utf-8"));
