Your embedFonts() specification (especially your 'fontpaths' argument)
*did* make a difference.  This function calls ghostscript to perform the
embedding and if ghostscript cannot find the PFB files it cannot embed
the font.  If the PDF file does not have embedded fonts, the PDF reader
will use (substitute) its own fonts and the result can look awful.
