ASCII VS. UNICODE
THE SHOWDOWN (EXPLANATION AND DEFINITION)
ASCII
ASCII was originally developed for communications and uses only seven bits per character, providing 128 combinations that include upper and lower case alphabetic letters, the numeric digits and special symbols such as the $ and %. ASCII includes definitions for 128 characters: 33 are non-printing control characters that affect how text and space is processed and 95 printable characters, including the space.
