如用户信息某一字段存在特殊字符，这导致JSON_DECODE返回NULL，现对微信服务器请求结果进行编码替换后在进行解析。

微信中用户信息的地址也出现了特殊字符吗？ 我目前还没有发现 |

有这种情况，我贴出的实例代码就是拉取到的一位用户的信息，而且这个CITY字段不同编码解析出来内容也不一样，导致JSON_DECODE无法解析。你把示例代码json直接用json_decode试一下就可以看出问题了 |

微信服务器会返回规定编码的字符串,我觉得特殊字符也会被微信端转换为UTF-8 ,所以目前应该无需考虑这个问题,之所以这里出现特殊字符,可能是楼主在浏览器直接访问接口时浏览器的编码为GBK或者GB18030,试着修改一下浏览器的默认编码为UTF-8 |

示例代码：
$str = '{"subscribe":1,"openid":"o7TC3v_zvuxmuRPU6YeBOD6cz0Ng","nickname":"文文","sex":2,"language":"zh_CN","city":"S�Y4","province":"Q���Sä","country":"","headimgurl":"http://wx.qlogo.cn/mmopen/0dhrpQA7Vn64H2u2zApyiaicEg4hk0UCIqrJP0EcRDh1z108ARaaWUYIDfmLvBXicxGpo4uWej1PjsdMZcWIdPQ7TJehRnLWaJD/0","subscribe_time":1482894792,"remark":"","groupid":0,"tagid_list":[]}';
json_decode($str, true); 返回NULL 主要原因是city字段含有特殊符合或表情符号
