[R] Printing Central European characters

[Barta Zoltan]

Dear R-users,

I have problems with printing Central European (CE) characters
(e.g. {\H o} and {\H u}) in graphics made by R.

After executing the following code I can see the CE characters with gv
on my screen, but I cannot print them on a postscript printer. 

> postscript(file="proba.ps",enc="ISOLatin2.enc")
> plot(0:15,0:15,type="n")
> grid(15,15,lty=1)
> for(i in c(32:127, 160:255)){x <- i %%16;y <- i%/% 16;points(x,y,pch=i)}
There were 50 or more warnings (use warnings() to see the first 50)
> warnings()
Warning messages:
1: font width unknown for character 127
2: font metrics unknown for character 127
3: font width unknown for character 127
4: font width unknown for character 160
5: font metrics unknown for character 160
6: font width unknown for character 160
7: font width unknown for character 161
8: font metrics unknown for character 161
9: font width unknown for character 161

language R                

Note, I have problems with characters for which a warning of 'font
width unknown for...'  printed. These characters are also not centered
on the grid in gv display. From latex there is no problem to print CE
characters. \psfrag also works fine.

Many thanks for your help.
