    }

}  

and i am expecting "question":"我们可以得到我们的家庭会议？" instead of "question": "??????????????",

please help me to sort out this issue. thanks in advance.

Answer 1

Try this simple code:

EDIT

    $str1 = base64_encode("我们可以得到我们的家庭会议？");
    $str2 = base64_decode($str1);
    echo $str2;

This gives the characters as they are. So, while sending the data to web service (from database) for question encode it and decode it again. Because the problem is with encoding for these characters.
