What is ASCII code 128?
ASCII (American Standard Code for Information Interchange) code 128 does not exist within the standard ASCII character set. The standard ASCII character set, which consists of 7-bit binary codes, includes characters from 0 to 127. These codes represent a range of characters, including letters, numbers, punctuation marks, control characters, and special symbols, but it does not go beyond 127.
ASCII code 128 would theoretically refer to an 8-bit extended ASCII code, but the extension of ASCII to 8 bits has led to various incompatible character encoding systems, such as ISO 8859-1 (Latin-1), ISO 8859-15 (Latin-9), and Windows-1252, among others. These extended character encodings include additional characters beyond the standard ASCII range to accommodate various languages and special symbols.
In these extended encodings, code points 128 and above are used for characters specific to particular languages or regions. For example, in ISO 8859-1 (Latin-1), code point 128 represents the Euro currency symbol (€), while in Windows-1252, it also represents the Euro symbol, along with other characters specific to the Windows character set.
It's important to note that modern text encoding standards like Unicode have largely replaced extended ASCII encodings for international text representation. Unicode provides a standardized way to represent characters from a wide range of languages and scripts, and it includes characters well beyond the 128-code point limit of standard ASCII.
In summary, there is no ASCII code 128 within the standard ASCII character set. However, when people refer to ASCII code 128, they may be thinking of extended ASCII or specific character encodings like ISO 8859-1 or Windows-1252, where code points 128 and above are used for additional characters and symbols.
