Fix UnicodeEncodeError

✅ Solution

UnicodeEncodeError usually arises when your code attempts to encode Unicode characters into a byte stream using an encoding that doesn't support those characters, often defaulting to ASCII. Fix this by explicitly specifying a UTF-8 encoding when opening or writing files, like `open("filename.txt", "w", encoding="utf-8")`, or set the `PYTHONIOENCODING` environment variable to `utf-8`. Also, ensure that your data source encoding matches the encoding you're using in your code.
