How to fix: "UnicodeDecodeError: 'ascii' codec can't decode byte"

The "UnicodeDecodeError: 'ascii' codec can't decode byte" error occurs when trying to decode non-ASCII bytes using the ASCII codec.

You can also use the decode method on the bytes to specify the codec:

content = b'...'.decode('utf-8')

It's important to note that the correct codec to use depends on the file you are trying to read. UTF-8 is a commonly used codec for text files, but other codecs such as UTF-16 and ISO-8859-1 may also be used.
