Should be "character", right?

+ with length 1. The built-in function :func:chr converts a + character to its codepoint (as an integer); :func:ord converts + an integer in range 0 - 10FFFF to the corresponding character.

Actually chr() converts an integer to a string and ord() converts a string to an integer. chr and ord are swapped in your text.

+ :meth:str.encode can be used to convert a :class:str to + :class:bytes using the given encoding, and :meth:bytes.decode can + be used to achieve the opposite.
