As far as I understand non-stream objects are taken and united to  
build one stream that can be better compressed. This is possible  
because PDF 1.5 offers new ways to refer to these objects. IMO the  
savings won't be so much, it makes more sense to imply compression  
images on other streams (audio, video). I'll check later whether  
there is some reasonable amount gained. For this I edited


and added the two lines


(\pdfcompresslevel=9 is already there) and "refreshed" the FMT files.  
This went fine, first PDF files created in PDF 1.5 can be displayed.

I think it makes also sense to add in the LaTeX source


to enable the use of real Unicode characters instead of TeX compounds  
for non-ASCII characters.



There are two major products that come out of Berkeley: LSD and UNIX.  
We don't believe this to be a coincidence.
