Jupyter 无法打开 json 文件，引用 UnicodeDecodeError

Question

Jupyter 在尝试打开目录中的 JSON 文件时抛出 UnicodeDecodeError。错误：

我正在尝试打开一个 JSON 文件，最终将其转换为 CSV。该文件是本地的并上传到 Jupyter。我已经设置了编码，在 Chrome 上它显示其编码是 utf-8，但我仍然抛出错误。我还应该尝试其他编码吗？

这是我正在使用的代码：

import pandas as pd
import json

with open('recalls.json') as file:
    json_data = json.load(file, encoding='utf-8')

我认为你应该在打开文件时指明编码：

with open('recalls.json', encoding='utf-8') as f:
    json_data = json.load(f)
