I've just tried
postscript("latin2.ps", enc="ISOLatin2.enc")
par(pty="s")
plot(c(0,15), c(0,15), type="n", xlab="", ylab="")
title("Centred chars in ISO Latin2")
grid(15, 15, lty=1)
for(i in c(32:127, 160:255)) {
x <- i %% 16
y <- i %/% 16
points(x, y, pch=i)
}
and apart from some missing centering information it looks like
a table of ISO Latin2 I looked up.
Now, it may well be that your idea of latin2 differs from that, in which
case you need to change "ISOLatin2.enc". If so, can you let us know
so we can correct the file.
(BTW, I am assuming you do have a viewer with fonts that is capable of
showing the characters that you say are missing, but that's worth
checking. In the test above the .enc file shows what is not defined.
Mine has one missing)

Use the form of the family argument that specifies 4 afm files.
However, `X11' afm files are probably not correct for postscript fonts,
and you still need to deal with encoding.

No. PostScript only knows about encoded strings.
