UnicodeEncodeError，我无法从json文件打印字典

Question

我在从API读取字典数据时遇到问题，我使用requests.get（）提取信息，并将其保存在json文件中，但当我想读取字典数据并从字典中提取货币时，它不允许我：

代码如下：

import requests
import json

endpoints = {"access_key": "*********************************"}
url = "http://api.currencylayer.com/list"

if __name__ == "__main__":
    response = requests.get(url, params=endpoints)
    data = response.text

    with open("simbolos.json", "w") as f:
        f.write(data)

with open("simbolos.json", "r") as f:
    json_file = json.load(f)
    print(json_file)

json文件创建得很好，当我尝试读取字典时，出现了错误occours，我可以看到json文件有很多未定义的字符，当我运行代码时，它也给了我这个错误：

UnicodeEncodeError:“charmap”编解码器无法对位置3878处的字符“\u02bb”进行编码：字符映射到

所以我认为这与编码utf-8有关，但我找不到解决问题的方法，我尝试使用解码和编码，但都是一样的，有解决方案吗，下面是创建的json文件：https://www.dropbox.com/s/q4f6w5q9ce2gn1i/simbolos.json?dl=0

我扩展了@lenz的评论

当您在文本文件上使用open（读/写）时，您应该始终添加编码：“显式优于隐式”（Python的一个咒语），但它可以帮助您（和其他人）在将来了解您期望的编码。可能情况并非如此（但仍然如此）：较小的字符集通常使用单字节，并且每个字节都可用，因此在这种情况下，通常只有错误的字符，但没有错误

所以我认为@lenz是对的

print将对终端功能的字符进行编码，因此有时只能使用一个子集。Linux和Mac使用UTF-8（通常），因此没有问题[但是LANG=C只支持ASCII]。通常Windows上的Python会出现问题：它仍然使用本地代码页（因此只有大约200个可用字符）

ASCII和Latin-1（Windows ANSI的基础）只支持少数货币符号。欧元符号创建得很晚（但这是添加到Windows中的备用代码）。窗口中不包括各种其他货币符号（但主要有5种：美元、英镑、日元、美分、欧元），还有许多货币符号（见a1）

因此，要在Windows上打印，您需要一个支持Unicode（并且告诉Python它使用Unicode）的终端。一种解决方法是只写一个文件，然后从该文件中读取数据（编辑器通常允许您选择编码，一些编辑器在文件更改时自动刷新数据）
