I have an Rmd file encoded with UTF-8, but when I knit the file, R evaluated inline and chunk contents are missing some Czech characters. Everything is fine when I type the text outside of chunks. Reading the same text from a file, I can correctly produce the output inline, but not when using printing (print or cat) from within a chunk. I am completely confused about the situation, especially the cat behaviour.
I am on Windows. Checking encoding in console returns UTF-8. Locale set to English_United Kingdom.1252.

title: "test"
output: html_document

```{r}
txt <- "Čeština funguje"
print(Encoding(txt))
print(txt) # prints incorrectly
```
Čeština funguje # prints correctly
`r txt` # prints incorrectly
```{r}
cat(txt) # prints incorrectly
```
```{r, results='asis'}
line <- readLines("line", encoding = "UTF-8")
print(Encoding(line))
print(line) # prints incorrectly
cat(line) # prints incorrectly
```
`r line` # prints correctly!
P.S. I know there has been a lot said about R and encoding on Windows, but despite my extensive searching I can't find a solution and don't fully understand this behaviour. I am guessing I need to set some locale, but my efforts so far have been in vain.
