我正在尝试将JSON文本文件转换为python对象（并将文本打印到控制台）我收到编码字符时出错。
我正在使用Python 3.6.5和Windows Powershell来执行脚本。
Python代码：
import json
f = open("z.txt", "r", encoding='utf-8')
test = f.readline()
testa = json.loads(test)
print(testa)
test = f.readline()
testb = json.loads(test)
print(testb)
f.close()
执行脚本的Powershell代码：
python tweetsentiment.py
带有JSON测试的文本文件：

UnicodeEncodeError: 'charmap' codec can't encode characters in position 685-687: character maps to <undefined>
我正在打开的文件包含从twitter中提取的两行json。第一行通过“testa”变量加载并打印到控制台。
然而，第二行，通过“testb”，在转换json时失败，返回上述错误代码。错误引用的位置685-687中的字符（如果我在正确的位置查找）在记事本++中打开时显示为“car” - 没有什么不寻常的。
我已经看过其他几十个与我的作品类似的帖子并尝试了所有的解决方案 - 不同的编码，没有编码，在命令行中使用“chcp”，添加“-sig”等 - 无济于事。
有谁知道这里的问题是什么？
Edit1：包含JSON文本 编辑2：建议的解决方案（添加.encode打印）不能解决问题。发生同样的错误。
