If a copyleft font is embedded in a document - such as a portion of a
TrueType font data file being copied into a PDF document file in order
for the document to always render using that font, even if the font is
not installed in the user's system - the PDF may be considered to be a
'combined work,' combining the fonts, images and texts into a single
work.
Just being one file does not imply it is a combined work.
After all, a tar file is one file, but the Emacs tar file
contains GPL-covered source code and GFDL-covered documentation.
(Those two licenses are not compatible.)
A PDF file is not exactly like a tar file, but maybe the conclusion
should be the same.
The GNU project's GPL FAQ has a section about this topic -
http://www.gnu.org/licenses/gpl-faq.html#FontException - which takes
the position that PDF font embedding _can_ be considered subject to
the GPL's copyleft and therefore suggests adding an 'additional
permission' that allows PDF embedded with GPL fonts:
It also says that this is an "exploratory essay."
The FSF will look further at this case.
