knitr losts accentuated characters when compiled in pdf

I read "all" demands concerning knitr and encoding but I cannot find solution... My problem seems very simple: Here is my Try.Rnw file:

\documentclass{article}
\usepackage[utf8]{inputenc}
\begin{document}
\section{Essai de données}   
<<>>=
a <- "éssaié"
print(a)
@
\end{document}

It is saved in UTF-8. When I compile it in Rstudio or directly in R with

knit2pdf("Try.Rnw", encoding = "UTF-8")

I get this pdf:

1 Essai de donnes
a <- "ssai"
print(a)

All the accentuated characters are lost. Same happened if I save it in LATIN1.

Thanks a lot

Marc

The problem may come from three possible sources: knitr, the encoding, or LaTeX. To diagnose the problem comes from knitr, you need to call knit() instead of knit2pdf() to see if the tex output is correct:

library(knitr)
knit("Try.Rnw", encoding = "UTF-8")
# open Try.tex and see if the accentuated characters are there

To make sure the encoding is really UTF-8, check the menu File --> Save with Encoding.
