[Rd] (PR#13234) Problems with Sweave and pdf.options(encoding="ISOLatin7")

[Prof Brian Ripley]

Just to close the loop on this, the following works in en_GB.utf8 on 2.8.0:

<<fig=TRUE,echo=TRUE,pdf.encoding=ISOLatin7>>=
pdf.options(enc="ISOLatin7")
ps.options(enc="ISOLatin7")
plot(rnorm(100),main="\u0105\u010D\u0117\u0119\u012F\u0161\u016B\u0173\u017E")
@

I think the point is that you can use different encodings for different
figures in one Sweave document.

But in R-devel you can now pass any option via the Sweave() call as I at 
least expected from the documentation.
