German umlauts disappear in output when qmd-file contain R code chunks

[tieying12]

Bug description

I have a qmd-file where the body contains text with german umlauts. Generating as output a pdf-file the umlauts are correct displayed. However if I insert a R code chunk in the qmd document the umlauts diappear in the pdf-file.

Steps to reproduce

`--- format: pdf: papersize: A4

pdf-engine: "pdflatex"

lang: de

execute: echo: false

Ich würde es über alle Maßen begrüßen

x <- 4

y <- x**x

Es wäre schön, wenn dies auch gehen würde.`

Expected behavior

Expected output in pdf document:

Ich würde es über alle Maßen begrüßen

Es wäre schön, wenn dies auch gehen würde.

---

I get this result when I remove the R code chunk

Actual behavior

output in pdf document:

Ich wrde es ber alle Ma<9f>en begr<9f>en

Es wre schn, wenn dies auch gehen wrde.1

Thanks for the report!

Could you format your code properly? Thanks.

You can share a Quarto document using the following syntax, i.e., using more backticks than you have in your document (usually four ````).

````qmd

Here is the Quarto document with R code chunk included:

---
format: 
  pdf: 
    papersize: A4

pdf-engine: "pdflatex"

lang: de

execute:
  echo: false
---

Ich würde es über alle Maßen begrüßen

```{r include=FALSE}

x <- 4

y <- x**x

Es wäre schön, wenn dies auch gehen würde.

Attached are the results with R code chunk included (test1.pdf) and without (test2.pdf)

I believe your LaTex Installation is faulty. I just edited a bit the code to make it more clear and Quarto-like.

include: true	include: false

[tieying12]

Thank you for your hint and for the clarification. When I worked with knitR and rmd-files I had never problems so I wrongly assumed my TeX Live installation is working correctly in any case.

[mcanouil]

To note, I am using TinyTex which can be install by Quarto.

[tieying12]

When I uninstalled my TeXLive and installed TinyTex with Quarto I got the same strange behaviour. While rendering with knitR the corresponding Rmd file I get a correct pdf output, but when rendering the qmd file with Quarto all Umlauts disappear. Meanwhile I found the cause. My R version was installed with linuxbrew. When I uninstalled R und reinstalled it using apt, everything works fine. It seems that Quarto has some problems when R and RStudio are installed by different tools, however knitR still works fine.

Thank you for using Quarto and reporting an issue!

Unfortunately, this issue is now considered stale because it has been opened since 14 days without providing a "working" reproducible example to help us investigate. If you are still facing the issue, please review the "Bug Reports" guide on how to provide a fully reproducible example as a self-contained Quarto document or a link to a Git repository. Without a reproducible example, it is unlikely that the issue will be addressed.
