In this lesson, we will look at character coding systems. First, we will consider character coding systems that you might have come across before, such as semaphore and Morse code, then we will be introduced to ASCII, a standard coding system for representing text. Next, we will learn about the need for Unicode to extend ASCII. Finally, we will learn how to work out the size of a plain text file.
