Every presentation space has a current character mode, which determines the extent to which a font can be affected by the attributes defined in CHARBUNDLE. The mode affects compatibility issues that are invisible to both the user and the programmer. The following table describes the character modes and their influences on the current font.
An application selects a character mode using GpiSetCharMode. When a mode is selected, it applies to any font (including the system font) used while the mode is current. The character mode takes effect when you draw character strings; it has no effect at the time you define a logical font.
