Claris CAD: Claris CAD Font and Undefined Characters

When I use the Claris CAD Font I see lines on the screen. I know that these characters should be symbols such as the degree symbol or the plus minus character. Why do these not show up?

This information was provided by Claris Corporation on 16 March 1998, and incorporated into Apple Computer's Tech Info Library.

The Claris CAD font does not define these symbols in versions prior to the one that shipped with Claris CAD 2.0v2.
