  • Extended ASCII (ISO/IEC 8859)

    The Extended ASCII character set extends the basic 7-bit ASCII range to 8-bits, to provide additional character encoding for broader character representation scenarios.

    It builds upon ISO/IEC 2022 which defined the initial 8-bit ASCII character set, with the C0 character set range replicating 7-bit ASCII and the C1 range covering extended control characters using character codes 128-159.

    The lower 7-bit ASCII range represents a standardised western (English) alphabet.
