extended ASCII
The second half of the ASCII character set (characters 128 through 255). Designed in the 1960s, ASCII was originally a 7-bit code (0 through 127). To accommodate foreign languages, the DOS code set added various characters; however, more than 200 extended ASCII encodings were developed. The Unicode character encoding was created to handle every language on the planet (see Unicode). |
