You will see it, however, in Adobe Reader. The TidBITS article noted that it happens only in “applications that rely on Mac OS X’s mechanism for rendering fonts programs like InDesign that have their own rendering engines are immune.” Surprisingly, the problem does not occur in Mac OS X’s own Preview application. The bug only crops up in certain applications.The problem primarily occurs with PDF files-especially PDF files you create in Mac OS X 10.6.7, such as via the “Save as PDF…” command in almost any application.
You can find out exactly which of your fonts are OpenType PostScript by launching FontBook and entering OpenType PostScript in the Search box. You are likely to have them, however, if you’ve installed certain third-party software, especially Adobe applications. As far as I can tell, Mac OS X does not install any such PostScript fonts.
