Wouldn't it be easier to set the default fonts, instead? I.e. 
getOption("X11fonts")? Then you would not have to specify the family for each 
separate plot. For postscript and pdf, apparently the default is to use 
postscript/pdfFonts("Helvetica"), so this could probably be changed globally 
as well, if needed.

For example, the following example works here (I don't have a "complicated" 
encoding to play with, so instead I chose a different font family):

fnts <- getOption("X11fonts")
fnts[1] <- "-adobe-palatino-%s-%s-*-*-%d-*-*-*-*-*-*-*"
options (X11fonts=fnts)

Then call plot without any family argument:
plot (1, 1, main="test", xlab="test2")

Can't do any harm to add this to plot_options. However, we'd probably need a 
whole dedicated tool to facilitate font selection, in order to make this 
useful.

Yes. View->Set Encoding (and in theory, it should auto-detect the encoding). 
On the other hand, what was the reason again, not to use a UTF-8 locale in 
the first place? Are there no matching fonts available for that?

It uses khtmlpart, so in essence, yes.
