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

2008/11/19 Prof Brian Ripley <ripley at stats.ox.ac.uk>:

I can't actually check what happens since the message has been garbled en
route to me.  Can you please send what you intended using \uxxxx escapes so
it is portable.  (What I have is what appears to be UTF-8 re-encoded in
UTF-8, things like c3 84 3f.)

And can you also confirm that the example works correctly directly in pdf()?

OK, the modified R code is:

plot(rnorm(100),main="\u0105\u010D\u0117\u0119\u012F\u0161\u016B\u0173\u017E")

It does not work correctly with Sweave, as I wrote in my email, I
rechecked. And yes it works if only pdf is used.

Hi,

Sweave for some reason does not respect encoding setting in pdf.options.

Rather it uses its own setting.  I think you need to set option
pdf.encoding="ISOLatin7" on the Sweave call.

Is it possible to do that? Sweave function in R, does not support
that, and using
SweaveHooks produced the same result.

It would probably be better if Sweave() fetched the default for
options$pdf.encoding from pdf.options(), and definitely that this was
documented.

I did not find any mention about encodings in ?Sweave, ?RweaveLatex
and ?Rtangle,  and Sweave manual and FAQ.
I looked at the code of RweaveLatexSetup, and saw that pdf.encoding is
defined explicitly, that is how I figured out, that
probably eps files are probably ok.

Sorry for the garbled message, next time I will send unicode portable
code without relying on email encodings.

Sincerely yours,
