[Rd] UTF8 markdown vignette

[Yihui Xie]

I took a look at the R source and I realized that the encoding was
actually never passed to the vignette engine:
https://github.com/wch/r-source/blob/e721ef5f4/src/library/tools/R/Vignettes.R#L507
Apparently only the file and quiet arguments are passed to the
vignette engine. Did I miss anything?

To Thierry: I explicitly asked for library(rmarkdown);sessionInfo(),
but you only told me the version of rmarkdown, which is not the only
thing I was asking for. It is extremely important in this case to know
the versions of other packages as well as your system locale
information.

Regards,
Yihui
