SyntaxError: Non-UTF-8 code starting with

This error message is commonly encountered when attempting to execute code that contains characters outside the UTF-8 character set. UTF-8 is a widely-used encoding standard that supports almost all characters in the Unicode character set, which includes characters from many different alphabets and scripts.

To resolve this issue, you should ensure that your code is saved in UTF-8 format, and that any input or output data is properly encoded and decoded using UTF-8. You should also check for any non-UTF-8 characters in your code or data, and either remove them or convert them to UTF-8.

If you are working with non-ASCII characters in your code or data, it may be helpful to use a tool like Python's built-in `codec` module to handle encoding and decoding. This module provides a range of functions for working with different character sets and encoding formats, including UTF-8.
