Ok, so I know this has been asked before. I use Acrobat 9...I know previous threads suggested to uncheck the "rely on system fonts only...etc". Which works and the gibberish goes away, but of course I can no longer use the Touchup Text tool without getting the dreaded "all or part of the selection has no available system font...etc". Then I also did my research and came across the adobe article http://kb2.adobe.com/cps/330/330971.php. But this doesn't help me. I don't want to have to go through this process for each individual text I want to modify. The story is, I was on Acrobat 8...but I had to upgrade to Win 7 64bit...so now I get this problem with Acrobat 9 (and X). 8 never had this issue...I would never get gibberish and could always modify the text without getting this font error. Anybody can help? Thanks in advance!
By moving into Windows 7 64-bit you've imposed upon yourself the requirment to upgrade the Windows based applications you use. This includes Acrobat. For Windows 7 64-bit you must have Acrobat X installed. Previous versions of Acrobat cannot be "co-installed" on the Win 7 box. Note that, by design, Adobe Reader X and Acrobat X can co-exist on the same box with no issues.
With Acrobat X installed you'd want to update to 10.1.0 which provides a PDFMaker that is compatible with 64-bit Office 2010 Word, Excel, & Powerpoint. Note that, currently, the Acrobat X PDFMaker is only compatible with the 32-bit versions of the other "2010" applications.See: PDFMaker compatibility matrixOnce you have a Win 7 box with just the Acrobat X product open Distiller. Look at the High Quality Print or the Press Quality Job Options. Both of these embed fonts. Look that over. Use that information to make a custom configured job option that embeds fonts / subsets of fonts; or, use High Quality Print or Press Quality.
You must have a job option in use that embeds fonts. The unchecked/unticked "Rely on system fonts;..." presumes PDF creation involves embedded fonts. However, it does not embed the fonts — that's done by the Distiller job option.
Properly configured, PDFMaker & the selected Distiller job option provide a PDF with embedded fonts / font subsets such that all characters are "present" when viewed - even if one's computer does not have (as OS aware system fonts) the fonts used available on one's computer.Also, when creating PDFs with PDFMaker try starting with the Adobe PDF virtual printer set as the "default". Then open the authoring application, master the content & output the PDF. You may find that using the old "tried & true" fonts rather than the newer ones found in Office 2007/2010 products is helpful.
Be well...
