title: German umlauts in R Markdown again
body: <p>I just want to make German umlauts (ü) work in R Markdown. I know there is already threads on this but I just can't get it to work. <a href="https://stackoverflow.com/questions/35671530/german-umlaut-characters-in-r-markdown">Here</a> Dirk EddelBüttel explains, that you simply need to enter proper unicode characters, how can I enter more properly than pressing the key?</p>
  
  <p>I want to knit the document into a pdf, so html work around is not an option. Anyway, it seems to be a problem of the Markdown side of the operation. I tried keeping the tex file and there the umlauts are already screwed.</p>
  
  <p>It would be really nice, if anyone could help.</p>
