What does Extended ASCII mean?
Extended ASCII, also known as "high ASCII" or "8-bit ASCII," is a collection of character sets that build upon the original 7-bit ASCII by using the full capacity of an 8-bit byte, allowing for 256 unique characters instead of just 128. The additional 128 characters (with decimal values ranging from 128 to 255) include various accented letters, special symbols, and graphical elements.
There are several extended ASCII character sets, such as ISO-8859-1 (also known as Latin-1), Windows-1252 (also known as CP1252), and others. These character sets were created to accommodate different languages and special characters that the original ASCII does not support. However, they are not universally standardized, and different systems or applications may use different extended ASCII sets.
