我无法读取文件,因为我收到“UnicodeDecodeError:‘utf-8’编解码器无法解码”错误

我有一个文件,想把它转换成utf8编码。

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 947: invalid continuation byte

我的目的是读取它,然后将其转换为utf8编码格式,但它不允许读取。

这是我的代码:

#convert all files into utf_8 format
import os
import io
path_directory="some path string"
directory = os.fsencode(path_directory)
for file in os.listdir(directory):
    file_name=os.fsdecode(file)
    file_path_source=path_directory+file_name
    file_path_dest="some address to destination file"
    with open(file_path_source,"r") as f1:
        text=f1.read()
    with io.open(file_path_dest,"w+",encoding='utf8') as f2:
        f2.write(text)
    file_path=""
    file_name=""
    text=None

误差为:

     14         f2.write(text)
