SyntaxError: Non-UTF-8 code starting with

This error typically occurs when there is a non-UTF-8 character or encoding present in the code. It can happen when the code is saved with a different encoding than UTF-8, or when non-UTF-8 characters are copied and pasted into the code.

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

1. Check the encoding of the file and make sure it is UTF-8. You can do this by opening the file in a text editor and checking the encoding settings.

2. If the file is not UTF-8, save it with UTF-8 encoding.

3. If you copied and pasted code from another source, make sure that the source is using UTF-8 encoding.

4. If the error persists, check the specific line of code where the error occurred and see if there are any non-UTF-8 characters present. Remove or replace these characters with UTF-8 characters.

5. If you are still having issues, try using a code editor that supports UTF-8 encoding and has the ability to convert files to UTF-8.
