The error message indicates that the Python interpreter has encountered a non-ASCII or non-UTF-8 character in the program, which is not compatible with the default encoding of the Python environment. Non-ASCII characters are those that are not found in the ASCII character set, such as characters from other languages or special characters like accents, symbols, emojis, etc. UTF-8 is a widely used encoding standard for representing characters from all languages in a uniform way. To avoid the error, the non-ASCII text should be encoded properly using a supported encoding such as UTF-8 or by including a special encoding declaration at the beginning of the Python file.
