This is very unlikely to have anything to do with Sweave, it's a 
graphics system problem.  You might want to read the article

Paul Murrell and Brian Ripley (2006) Non-standard fonts in PostScript 
and PDF graphics. R News, 6(2):41–47. 
http://cran.r-project.org/doc/Rnews/Rnews_2006-2.pdf

for information.  It looks as though you did everything it recommends, 
except embedding the fonts:  maybe you need to do that.
