R help - Jun 2005 - problem with postcript() and umlauts

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,
I am running R 2.01 on SuSE 9.2 and I use GNU-Emacs and ESS.
When using umlauts like ?? ?? ?? ?? for e.g. plot titles , I enter them
directly in the code, like

plot(seq(from=-4,to=4,length=100),dnorm(seq(from=-4,to=4,length=100)),main="Gau??-Verteilung")

I get a dotted box just after the "Gau" and before the "??"
in the title.

Using the postscript device

postscript()
plot(seq(from=-4,to=4,length=100),dnorm(seq(from=-4,to=4,length=100)),main="Gau??-Verteilung")
dev.off()

I get two warning messages:

Warning messages:
1: font width unknown for character 142
2: font width unknown for character 142
and a space after the "Gau" and before the "??".

I'd like to get rid of the extra space and the box before umlauts.
Does anyone know how to solve the problem?

Thanks,
~      Henning

That's the first time I have heard ? called an umlaut!

This sounds like an encoding problem, perhaps using Latin-1 in a UTF-8 
locale or vice versa.  In particular, R 2.0.1 (there is no 2.01) is out of 
date and has far less support for non-English locales than 2.1.1, and none 
for UTF-8 locales (which I believe SuSE 9.x uses by default).

So please follow the advice in the posting guide and update your R.
Your example works for me in 2.1.1 in both Latin-1 and UTF-8 locales.

Your email has been re-encoded several times en route to me, and does not 
contain character 142 (which is not a valid char in Latin-1 or UTF-8).
