UnicodeDecodeError: ‘ascii‘ codec can‘t decode byte 0xe4

This error occurs when trying to decode a byte string that contains non-ASCII characters using the ASCII codec. The byte string contains a character that is not part of the ASCII character set.

To fix this error, you need to decode the byte string using the correct codec that supports the character set used in the string. For example, if the string contains characters from the UTF-8 character set, you can decode it using the UTF-8 codec:

byte_string = b'some byte string with non-ASCII characters'

# Decode using UTF-8 codec
string = byte_string.decode('utf-8')

Alternatively, you can specify the codec when opening the file that contains the byte string:

# Open file with UTF-8 encoding
with open('filename', encoding='utf-8') as f:
    byte_string = f.read()

# Decode byte string
string = byte_string.decode('utf-8')
