I'm trying to read the content of a text file, line by line, with this code:

import os.path  



file_to_read = open("file_name.txt", "r")  

lines = file_to_read.readlines()

When I run it I get the following error:

Traceback (most recent call last):

File "D:/Files/test.py", line 4, in < module>

lines = file_to_read.readlines()

File "C:Program Files (x86)Microsoft Visual StudioSharedPython39_64libencodingscp1252.py", line 23, in decode
return codecs.charmap_decode(input,self.errors,decoding_table)[0]

UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 260: character maps to < undefined>

If I remove the last line, so the code looks like this:

import os.path  



file_to_read = open("file_name.txt", "r")  

Then I don't get any errors.

Which points me towards a problem with lines = file_to_read.readlines(), but I cannot see anything wrong with it.
