The FontShop plugin is a previewing tool, designed to give you an idea of how fonts may work in your designs before you buy them. It does not have the precision of a production design tool. Previews cannot be 100% accurate, and of course fonts have varying characteristics such as width which can make substitution unpredictable. If you are using paragraph type, you may get more predictable results by either converting your text field to point type, or specifying line-breaks manually and creating a very wide type bounding box for your paragraph.
Previews cannot be 100% accurate, and of course fonts have varying characteristics such as width which can make a substitution problematic. Word wrapping is especially unpredictable. Nevertheless we hope to improve the accuracy of previews in future releases.
