Working with Characters and Codes

Every character that you can display on your screen has its own underlying numeric code. For example, the code for the uppercase letter A is 65, while the code for the ampersand (&) is 38. These codes apply not only to the alphanumeric characters accessible via your keyboard, but also to “extra” characters that you can display by entering the appropriate code. The collection of these characters is called the ANSI character set, and the numbers assigned to each character are called the ANSI codes.

For example, the ANSI code for the copyright character (©) is 169. To display this character, press Alt+0169, where you use your keyboard's numeric keypad to enter the digits (always including the leading zero for codes higher than 127).
