switch语句有问题？

public class HelloWorld {
    public static void main(String[] args) {
  char today='日';
  switch(today)
        {
            case '一':
            case '三':
            case '五':
                System.out.println("吃包子");
                break;
            case '二':
            case '四':
            case '六':
                System.out.println("吃油条");
                break;
            default:
                System.out.println("吃主席套餐");
        }
    }
}
