I'm using Pagemaker 7.0.1a on WinXP. Some fonts such as Sanvito (open type) and Myriad Pro (true type) appear fine in PM but do not convert to PDF where they appear as X placeholders as shown below. Top group is Sanvito, bottom is Myriad, Times worked OK. On the other hand, they convert just fine when converting MS Word to a PDF. My system uses Acrobat Distiller 7. Can anyone explain why this is happening?
Because PageMaker has been a dead program for nearly a decade and is known not to work reliably on the newest OSs, including XP, while Word is still being developed. If I were you, Iwould move on to InDesign while the generous discount upgrade from PageMaker is still available. I wouldn't be surprised if the offer expires when CS5 comes out.
The usual reason is that PM can not handle the full set of characters of an Opentype font.
