某些使用新字符串的字节数组（字节[]，“ UTF-8”）在jdk 1.7和1.8中返回不同的结果

byte[] bytes1 = {55, 93, 97, -13, 4, 8, 29, 26, -68, -4, -26, -94, -37, 32, -41, 88};
        String str1 = new String(bytes1,"UTF-8");
        System.out.println(str1.length());

        byte[] out1 = str1.getBytes("UTF-8");
        System.out.println(out1.length);
        System.out.println(Arrays.toString(out1));

byte[] bytes2 = {65, -103, -103, 73, 32, 68, 49, 73, -1, -30, -1, -103, -92, 11, -32, -30};
        String str2 = new String(bytes2,"UTF-8");
        System.out.println(str2.length());

        byte[] out2 = str2.getBytes("UTF-8");
        System.out.println(out2.length);
        System.out.println(Arrays.toString(out2));

bytes2使用新的String（byte []，“ UTF-8”），结果（str2）在jdk7和jdk8中不相同，但byte1相同。bytes2有什么特别之处？

测试“ ISO-8859-1”代码，bytes2的结果与jdk1.8中的相同！
