DocsASCII Codes
ASCII (American Standard Code for Information Interchange) is a character encoding based on the English alphabet. It assigns a number to represent each letter of the alphabet (with separate codes for upper case and lower case letters), each numerical digit (from 0-9) and to some other important characters. These numbers are referred to as ASCII codes.
The following is a list of ASCII codes and their associated characters.
