最近项目需要用到unionid，故对encryptedData 进行解密操作，encryptedData，session_key，iv已正常拿到，解密出的字符串数据，nickName是中文而导致乱码，但某些用户，nickName乱码后会导致nickName对象的数据少个"引号从而导致转JSON对象失败报异常，下面放截图。

正常的数据：

{"openId":"o80ME5lIrkOg0mVw9jn2l0QcEz-g","nickName":"bocn","gender":1,"language":"zh_CN","city":"Haikou","province":"Hainan","country":"China","avatarUrl":"https://thirdwx.qlogo.cn/mmopen/vi_32/Q0j4TwGTfTJnd1BOQXoe1OwqW1VWmtKd8XRPERomtQ1ykacCr09KLSAkNyZvrq9P8V1APUwrricVhKY8wtLWiaqw/132","unionId":"oaDqW6KKh14nlRqPWLuwkNDkG2b0","watermark":{"timestamp":1602294120,"appid":"wxa7d216c55bad2edb"}}

异常的数据：

{"openId":"o80ME5qCi7U6QaSsqJpDTfVHWjgw","nickName":"宀佹湀鏄妸鏉?尓鍒?,"gender":1,"language":"zh_CN","city":"East","province":"Hainan","country":"China","avatarUrl":"https://thirdwx.qlogo.cn/mmopen/vi_32/Q0j4TwGTfTKABUOialWDJn1T2aWjiaAonickP34X6gibicp9qerPvnA74C6N9XHQH6p3dtp9LY6tvWVony0W9h4LnSg/132","unionId":"oaDqW6BPlOKL9KXgmRCzgiEgs6KQ","watermark":{"timestamp":1602293682,"appid":"wxa7d216c55bad2edb"}}

这个nickName是纯中文的，但是开发中发现有些用户nickName是纯中文乱码，引号也正常返回的。

在此求助各位。。。
