R help - Mar 2014 - UTF-8 characters in pandoc template variables using knitr

Dear all,

Consider the simpel RMarkdown file below. I've saved it as test.md with
UTF-8 encoding. Notice that I have embedded a custom pandoc variable
'test' in the file. This variable holds an UTF-8 character ?.

%My title
%The authorslist
<!--pandoc
format: latex
V: test:"Copyright notice. ? copyright holder"
-->
# First section

fgsdfg jsdksdfgsdfg

Now I try to compile it from within R using knitr.

library(knitr)
pandoc("test.md", format = "latex")

knitr inserts an extra character in the system command to pandoc. I assume it
has something to do with the encoding. Any suggestions on how to solve this?

executing pandoc -V test:"Copyright notice. ?? copyright holder"  -f
markdown -t latex -o test.pdf "test.md"

I've posted the question last week on StackOverflow
(http://stackoverflow.com/questions/22198832/utf-8-characters-in-pandoc-template-variables-using-knitr)
but did not got any response.

Best regards,

Thierry

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.
