R help - Jul 2002 - problem with german fonts (gnu-emacs 21.2.1, ess-5.1.21, w95)

I have a little problem, I cannot solve (at least reasonable fast)
I use gnu-emacs 21.2.1 with r-1.5.1 on windows 95. In recent versions
I changed "process-coding-system-alist" (C-x[REt]p) to
"latin-1". Then I was
able to plot german "????" etc(rgui does make this correct). 
With the new R version this does not work any
more. I tried to use some other codings systems (iso-latin-1, etc.) and also
tried 

postscript("c:/temp/temp.ps",encdoding="ISOLatin1.enc")

in combination with some coding systems. Nothing work: 
> postscript("c:/temp/temp.ps",encoding="ISOLatin1.enc")
> plot(1,1);text(1,1,"???")#latin  1 --no warning wrong result
> plot(1,1);text(1,1,"???")#iso-latin-1 -no w.w.r.
> plot(1,1);text(1,1,"???")#dos

...all this produce wrong fonts. I had the same problem recently 
at home on debian-stable. Does anybody has a solution?
