1.背景

因为需要windows下进行flink测试，于是在windows下开启kafka，然后拷贝一段数据，使用comsole去发送数据，此时发现数据在解析的时候报错

org.apache.flink.shaded.jackson2.com.fasterxml.jackson.core.JsonParseException: Invalid UTF-8 middle byte 0xc0
at [source: (byte[])"( "fileName": "user","eventCount": "1", "srcPort": "32691","deviceName": "192.168.84.23", "deviceId": "12345604", " responseCode": "400","destAddress": "10.1.1.22","destHostName": "172.16.101.164", "srcGeoLongitude":"-95.71289",
"srcGeoLatitude": "37 .09024","deviceCat": "/Audit", "eventId":"5409001249409249025", " srcGeoCity": "б","srcAddress": "20.1.1.6",
"srcGeoCountry":"ẞ00↓","productvendorName": "ẞ"

大概是中文乱码，但是有个我首先觉得是编码问题，于是我把数据保存在txt文档中，并且保存的时候设置UTF-8编码，发现不行。（这个在我同事那里挺好用的）。

然后我将cmd黑窗口设置utf-8，发现也不可以。修改编码参考：https://jingyan.baidu.com/article/d621e8da6565ba2864913f47.html
