Translation:
There are two meanings to 'CHAR(5)': either it means 'a character string consisting of 5 bytes' (that is called 'byte semantics') or 'a character string consisting of 5 characters' (this is called 'character semantics').

Translation:
A character is, technically speaking, an entry in the list of all possible characters. This list is called character set (or codepage).
