UnicodeDecodeError: ‘charmap’ Codec Can’t Decode Byte X In Position Y: Character Maps To

This error usually occurs when trying to decode or read a file that contains characters that are not supported by the character encoding of your system.

To fix this issue, you can try the following steps:

  1. Specify the correct encoding when opening the file using the open function. For example, if the file is encoded in UTF-8, you can do:
with open('file.txt', 'r', encoding='utf-8') as file:
    # Code to read the file here
  1. If you don’t know the exact encoding of the file, you can try using the chardet library to automatically detect the encoding. Install it by running pip install chardet and then use it in your code like this:
import chardet

with open('file.txt', 'rb') as file:
    raw_data = file.read()
    detected_encoding = chardet.detect(raw_data)['encoding']

with open('file.txt', 'r', encoding=detected_encoding) as file:
    # Code to read the file here
  1. If the above steps don’t work, you might have to manually inspect the file and determine its correct encoding. You can then use that encoding to open the file.

By specifying the correct encoding, Python will be able to decode the file’s contents without encountering the UnicodeDecodeError.
