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 main problem with the basic ASCII character set (ASCII codes 0-127) is that it was defined and published to target English language data only. The extended character set aims to address that for Latin-based alphabets. The revised standard is split into 16 parts. For example, part 1 refers to ‘Western European’ languages and is denoted by a -1 suffix on the standard (ISO/IEC 8859-1).
For each higher-range ‘part’ (codes 128+) the first 32 characters should follow the ISO/IEC 2022 C1 character control set. Codes 128 and 129 were deprecated in a later draft of the C1 set and are available for use by specific encoding schemes. In ISO/IEC 8859-1, code 128 is the EURO currency symbol (€).
