使用pandas读取CSV文件时持续遭遇UnicodeDecodeError编码错误的求助

我正在尝试用pandas打开一个CSV文件：

import pandas as pd 
df = pd.read_csv('/file/planned.csv') 

这个文件里有从全球各地收集来的约2000条记录，但打开时直接报了编码错误：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xec in position 34: invalid continuation byte

之后我查了一些资料，试着换了几种编码格式来读取，但每种都遇到了对应的错误，还是没法成功：

utf-8 #

df_planned = pd.read_csv('/content/sample_data/planned.csv', encoding='utf-8')

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xec in position 34: invalid continuation byte

utf-16 #

df_planned = pd.read_csv('/content/sample_data/planned.csv', encoding='utf-16') 

UnicodeDecodeError: 'utf-16-le' codec can't decode bytes in position 234-235: illegal encoding

euc-kr #

df_planned = pd.read_csv('/content/sample_data/planned.csv', encoding='euc-kr')

UnicodeDecodeError: 'euc_kr' codec can't decode byte 0x84 in position 37: illegal multibyte sequence

cp949 #

df_planned = pd.read_csv('/content/sample_data/planned.csv', encoding='cp949')

UnicodeDecodeError: 'cp949' codec can't decode byte 0xe8 in position 43: illegal multibyte sequence

现在我还是没法把这个文件读取成pandas的DataFrame，有没有大佬能给我出出主意？非常感谢！
