[Rd] UTF8 markdown vignette

[ONKELINX, Thierry]

Dear Duncan,

The UTF-8 characters aren't properly rendered in the pdf version of the vignette.
$£€ âêîûô äëïöüÿ áéíóúý àèìòù ãñ çµ is rendered as $£€ âêîûô äëïöüÿ áéà óúý à èìòù ãñçµ

The same problem occurs when I use render("vignette.md", output_format = "mypackage::mystyle"), instead of render("vignette.md", output_format = "mypackage::mystyle", encoding = "UTF-8"). The default value of the encoding argument of rmarkdown::render() is encoding = getOption("encoding"), which is "native.enc" on my system.

I'll post the question on an RStudio forum as well.

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.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.

You don't describe the symptoms of "failing to recognize", but from the look of it, this is a problem with the knitr::rmarkdown engine or with the devtools packaging, so you should probably ask on an RStudio forum.
