Appendix C. Codesets

Table C-1 shows 256 decimal and hexadecimal codes that represent characters and control characters in different codesets. The codesets shown are:

  • ISO 8859 Latin-1 codeset. ISO 8859-1 is identical to the first 256 Unicode characters.

  • ANSI_X3.4-1968 ASCII. The ASCII characters are a subset of the 8859-1 code, and codes within the ASCII range are indicated by shading in the leftmost column in the table below.

  • IBM's nearly obsolete EBCDIC codeset.
