R Markdown won't Knit

  The file "EDA_1조.Rmd" should be encoded in UTF-8. Now I will try to read it with the system native encoding (which may not be correct). We will only support UTF-8 in the near future. Please see https://yihui.name/en/2018/11/biggest-regret-knitr/ for more info.

Somehow my Rmarkdown file won't knit into a html file. I've tried reopen with encoding to UTF-8 so far and did not have any luck.

Can someone tell me how to resolve this problem?

When you say you reopened it in UTF-8, do you mean that you followed the advice from Yihui's blog post to change the default RStudio encoding to UTF-8?

Also, do you get the same result when you click the Knit HTML button as you do when running the render() function in the R console?
