extended ASCII

[ik¦sten·dəd ′as‚kē]
(communications)
An addition to the standard American Standard Code for Information Interchange, namely, characters 128 through 255; includes letters with diacritics, Greek letters, and special symbols.

extended ASCII

The second half of the ASCII character set (characters 128 through 255). Extended ASCII symbols are different for each font. The standard font in DOS uses extended ASCII for foreign language letters as well as characters that make up simple charts and diagrams (see ASCII chart). The Macintosh allows extended ASCII characters to be user defined.

The extended ASCII characters in most Windows fonts are defined by ANSI for foreign languages, and the Character Map utility can be used to view them.

The rest of the possible characters, represented by the numbers, 128 through 255, were originally defined on PCs by an unofficial standard called IBM extended ASCII. This former industry standard has now been replaced for Windows-based applications by Microsoft's extended character set.(1) There is, however, one important library application that does not use either the Windows or IBM extended character set definition: the MARC record.
