Code pages and extended code pages

A code page maps each character of text to the characters in a character set or to the characters associated to a Unicode point. Two types of code pages exist:

  • A traditional code page includes EBCDIC or ASCII encodings only; it can be used with FOCA character sets and TrueType and OpenType fonts.
  • An extended code page includes multiple encodings within a single code page and can contain EBCDIC or ASCII encodings along with the Unicode equivalent value; it can be used with TrueType and OpenType fonts.

AFP outline fonts and AFP raster fonts use traditional code pages to map each character of text to the characters in a character set. TrueType and OpenType fonts use traditional and extended code pages to map each character of text to the characters associated with a Unicode point.

Each code point in an extended code page can be mapped to one or more Unicode values. Extended code pages allow code pages that contain user-defined characters (that is, those characters that have not been registered with IBM and assigned a GCGID value) to be used with TrueType and OpenType fonts.

The next table shows the extended code page files that you can download from the IBM Extended Code Pages web page.
