When exporting layouts to the WMF image format, the fonts cannot be viewed on a machine that does not have the ESRI fonts installed. To get around this problem the image is usually inserted into a Power Point slide, Word document, or an Adobe document to save the image and embed the fonts. However, when saving the document and embedding the fonts in the WMF image that contains the highway shield symbols the application used to create the document may return the following error:"ESRI Transportation fonts cannot be embedded because of licensing restrictions."
The highway shield symbols come from the Transportation and Municipal font (esri_6.ttf), which cannot be embedded due to a limitation with the font.
