Fix UnicodeDecodeError

✅ Solution

UnicodeDecodeError arises when Python tries to decode a byte sequence into a string using the wrong encoding. Specify the correct encoding when opening files or decoding byte strings, often 'utf-8' is the universal solution. For example, use `open("file.txt", "r", encoding="utf-8")` or `byte_string.decode("utf-8", errors='ignore')`, where errors='ignore' can help to ignore invalid characters.
