[Rd] UTF8 markdown vignette

Dear all,

I'm trying to use a Markdown vignette with UTF-8 encoding. It compiles well when knitting the vignette in RStudio, but it fails to recognize the UTF-8 settings when building the source package. Can someone point out what I'm doing wrong? I tried to put the relevant information below.

Best regards,



Using 64-bit R 3.1.2 with encoding = "native.enc" on Windows 7 with Rstudio 0.97.1091.

The source packages is build using the devtools package. The build command is R --vanilla CMD build  "myPackage" --no-manual  --no-resave-data

The DESCRIPTION file has

VignetteBuilder: knitr
Suggests: knitr
Imports: rmarkdown

The markdown vignette YAML contains
vignette: >
  %\VignetteIndexEntry{The title}

The custom output style converts the markdown to beamer with the --latex-engine = xelatex flag.

The vignette in tar.gz passes R --vanilla CMD check  --timings --as-cran

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.
