R devel - Oct 2008 - Problems with Sweave and pdf.options(encoding="ISOLatin7") (PR#13234)

Hi,

Sweave for some reason does not respect encoding setting in pdf.options.
Everything is OK with ps.options. Thus when using non-default encoding
for graphs, resulting graphics eps file is correct, but  pdf file is
not. Workaround is very simple, just use latex->dvips->ps2pdf chain to
get the intended pdf document. I tried to find the explanation for this,
but I did not find anything. If this is documented behaviour, I am sorry
for the disturbance.

After Sweaving the file below, pdflatex and latex->dvips->ps2pdf will
produce different pdfs. The tex file compiled succesfully in Ubuntu
8.04, and TeXLive 2007.

Sincerely yours,

Vaidotas Zemlys

Note the Lithuanian letters in latex will not display correctly, you
need
additional package. This does not matter to R, since we use Unicode and
pass the
correct encoding.

ps.options(enc="ISOLatin7")

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()?

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

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