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

[Prof Brian Ripley]

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.
