Graphic character sets
In addition to code page definition, IBM defines a subset of
printable characters within a nationalised code page, by
specifying a Graphic Character Set Global Identifier (CGSGID).
On an IBM band or daisywheel printer, any character which does
not appear within the subset of the code page, defined by the
CGSGID is substituted with the error character (hyphen). This is
due to the physical limitations of these types of printers and is
not appropriate for a laser printer, where all characters are always
available. Therefore, the XCTO design ignores CGSGID
assignments and allows all characters within the code page to be
accessed regardless of the CGSGID assignment.
