Both these functions accept an argument that encodes Unicode character, and the default for both these functions is UTF-8. If there was no special string representation for a bytes object, printing bytes would be nonsense. In this guide, we only used the UTF-8 encoding, which is the most popular encoding type. However, if someone is unfamiliar with Python, we will explain the notion. Lets examine the following example. In this situation, you should determine the right character encoding before encoding/decoding. In the above code, this isnt clear as you can just read the bAlice very clearly.
