如何使用utf-8编码读取bson文件

Question

我想读取一个具有utf-8编码的bson文件，但我不知道在哪里插入编码格式。

这是我的代码：

with open('filename.bson','rb') as f:
data = bson.decode_all(f.read())

Answer 1

您可以在open函数中插入编码

with open('filename.bson','rb', encoding='utf-8') as f:
data = bson.decode_all(f.read())

Answer 2

import io
f = io.open('filename.bson', mode='rb', encoding='utf-8')
