How can I write special characters in RMarkdown latex documents?

I am trying ot write a paper in RMarkdown pdf. But I dont know how to use special characters like "İ, ı, ğ, ü, ö". Those characters are present in Turkish. I can easily use them in Latex using e.g. \u{g} – ğ, \c{c} – ç, \”{u} – ü, {\i} – ı, etc.

Could you please tell how can I do the same in RMarkdown?

And where can I find some Rmarkdown paper or book templates?

Solution

  • HTML codes for Turkish characters will work (example from wikipedia):

    ---
title: "My doc"
output: pdf_document
---

HTML      char  detail                            anglicized
-------   --    ------------------------------    ---
Ğ   Ğ       Uppercase "G" with breve accent   gh1
İ     İ     Uppercase dotted "I"²               i (as in "tree")
Ş     Ş     Uppercase "S" with cedilla          sh
ğ     ğ     Lowercase "g" with breve accent   gh1
ı     ı     Lowercase dotless "i"³              ou (as in "in")
ş     ş     Lowercase "s" with cedilla          sh
-------   --    -------------------------------   --

    Which renders the PDF like this:

    For article templates, see the rticles package, or make your own

    For book templates, have a look at pandoc ebook, gitbook and bookdown

    This xelatex option I initially suggested will not work for Turkish characters:

    The xelatex engine is recommended for this kind of thing. Then you can access your system fonts with the mainfont argument:

    ---
title: "My doc"
output:
  pdf_document:
    latex_engine: xelatex
mainfont: "name of your system font that has all those characters"
---

PDF output will be in the font you specify. 

Just type as normal with no special codes.
