Appendix D Character-Translation Table File Formats

A character-translation table is used by Microsoft Windows and the
Microsoft Windows Universal Printer Driver to remap characters from the
printer's native character and symbol set to the Windows ANSI set. The
Universal Printer Driver will provide support for some of the common code
pages and symbol sets, so that this data will not need to be redundant in a
large number of individual printer drivers. It is intended that printer
drivers supporting devices with less common code pages and symbol sets will
contain their own character-translation table resources. Any given driver
can mix and match either of these types of character-translation tables as
needed. Character-translation tables provided by the Universal Printer
Driver are referenced from the minidriver through negative numbers that
correspond to the resource ID values (from the Universal Printer Driver),
and character-translation tables provided by the minidriver are referenced
by positive numbers corresponding to the resource ID values (from the
minidriver).
