使用 utf-8 编码和解码返回 UnicodeError

Question

I am both enconding and decoding with utf-8 but still I get a UnicodeError.

import pandas as pd
df.to_csv('myfile.csv', index=False, encoding='utf-8')

Then, in another.py, same project

import pandas as pd
with open(file, 'r') as f:
    csv = pd.read_csv(f, encoding='utf-8')

The error is: UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 51956: character maps to <undefined> This is not the first time I get this issue.

Answer 1

Ok, found it. Makes a lot of sense now.

with open(file, 'r', encoding='utf-8') as f:
    csv = pd.read_csv(f)
