Why pandas to_excel function has error encode sometimes?

Here's the code

import pandas as pd

error_code_link_lst = []
error_code_link_lst.append('twdJK7dzQR_x298_x298_x49147_x')
error_code_link_lst.append('1665207170810_x828_x1470_x745770_x.jpg')  # _x1470_     ᑰ
error_code_link_lst.append('h4fdn32sjG_x593_x593_x199560_x')
error_code_link_lst.append('xEQpZ7JjkZ_x288_x288_x3108_x')            # _x3108_     ㄈ
error_code_link_lst.append('SGkZYZKCRR_x298_x298_x49147_x')

df = pd.DataFrame()
df['link'] = [i for i in error_code_link_lst]
for i in df['link']:
    print(i)
df.to_excel('error.xlsx', i开发者_运维知识库ndex=None)

Output in terminal is right:

twdJK7dzQR_x298_x298_x49147_x
1665207170810_x828_x1470_x745770_x.jpg
h4fdn32sjG_x593_x593_x199560_x
xEQpZ7JjkZ_x288_x288_x3108_x
SGkZYZKCRR_x298_x298_x49147_x

But in the xlsx file, it looks like in a wrong encoding

xEQpZ7JjkZ_x288_x288ㄈx
SGkZYZKCRR_x298_x298_x49147_x

It seems like _x1470_ -> ᑰ and _x3108_ -> ㄈ.

I try to use df.to_excel('error.xlsx', index=None, encoding='utf-8'), but it not works as well.

I wonder why and how can I get the right data. Thanks!

Try specifying encoding='utf8' as parameter in to_excel function. Excel screenshot
