As Sharon Zardetto explains in “ Take Control of Fonts in Snow Leopard,” OpenType isn’t so much a font technology as it is a font format, created by Adobe and Microsoft. The problem seems to be restricted to OpenType PostScript fonts.
Be careful here, since PDFs with OpenType PostScript fonts created in 10.6.7 will have this problem forever, which could result in problems well into the future.
#MAC FONT MANAGER FONTCASE PDF#
The Flash Professional authoring tool relies on the platform’s font rendering, which explains why it’s having trouble too.Īs for why affected PDFs work fine in Preview but not in other programs, that’s a side effect of the fact that Preview doesn’t pay attention to the entire PDF specification (for instance, it also ignores color spaces, thus avoiding problems with badly structured PDFs that manifest themselves in Adobe Reader and Acrobat Professional).
#MAC FONT MANAGER FONTCASE MAC OS X#
Since Mac OS X uses PDF as the print spool format, that accounts for both PDF files and print jobs showing the problem. That said, the bug will affectĪll Mac applications that rely on Mac OS X’s mechanism for rendering fonts programs like InDesign that have their own rendering engines are immune.Īccording to my sources, the problem is that each font used in a PDF has a description of how the glyphs are encoded, and a change in 10.6.7 resulted in PDFs ending up with an incorrect encoding definition. (These PDF files work correctly in Preview, but may cause problems in Adobe Reader and Adobe Acrobat on the Mac and in Windows.) We’ve even seen reports of font problems when developing in Flash Professional. Others are experiencing problems when creating PDF documents using OpenType PostScript fonts. In particular, people are reporting errors when printing using certain fonts from Word and Pages, among other programs. In a nutshell, font rendering with 10.6.7 is breaking when certain types of fonts are used. That, however, is precisely what has happened with last week’s release of Mac OS X 10.6.7 (21 March 2011), which, among much else, fixes security vulnerabilities related to font handling. #1650: Cloud storage changes for Box, Dropbox, Google Drive, and OneDrive quirky printing problemĪs the bugs targeted by minor releases to Mac OS X 10.6 Snow Leopard become increasingly specific, it’s easy to become complacent about the possibility of an update introducing a new problem.
