Abstract
The present invention provides a method and apparatus in a data processing system for printing characters. Data received include glyphs for output on an output device, wherein the glyphs are to be output using a selected device font. A list containing all device font supported glyphs is passed to the operating system. Monitoring for unsupported glyphs in the selected device font is performed by the operating system. In response to detecting a glyph unsupported by the selected device font, a backup system font is used to output the glyph to the output device.
