Thanks for flagging this! :)

Can you show me an example of Japanese input, and the garbled output, so I can have a look at what the issue is?

from oxforddown.

The part before "Why use it?" in the Introduction is now in Japanese as attached.
BTW, Is this the correct way to contact you?

オックスフォード大学で自分の博士論文を書く際に作成したRMark-down用の論文テンプレート、oxforddown [@lyngsOxforddown2019]へようこそ。このテンプレートでは、RMarkdownで書きながら、美しく実績のあるOxThesisLaTeXテンプレートでPDF出力をフォーマットすることができ，かつ，長い間使われてきた美しいOxThesisLaTeXテンプレートでPDF出力をフォーマットすることができます。my own PhD thesis at the University of Oxford.
もしあなたがTeXやLaTeXを使ったことがないのであればR Markdownで論文を書くことで、OxThesisテンプレートへのより良いインターフェイスを提供できることを願っています。さらに重要なことは、R Markdownを使うと、論文の中にコードの塊を埋め込むことができ、コピー＆ペーストの手順を避けて、基礎となるデータから直接プロットや表を生成することができるということです。これにより、再現可能な研究を行う習慣が身に付き、研究者としての長期的な利益となり、将来的にあなたの結果を再現したり構築したりしようとする人の助けにもなるのです。

Fonts are specified: "MS Mincho" for Japanese and Times "New Roman for Roman" for Europe, US matters.

I just looked into this:

As per this latex stack exchange, one way to write Japanese characters in LaTeX is to

• use the xelatex LaTeX engine instead of pdflatex (which oxforddown uses by default)
• add the LaTeX package xeCJK

To do this with oxforddown, adjust the 'output details' section of index.Rmd to the following:

header-includes:
  - \usepackage{xeCJK}
output:
  bookdown::pdf_book:
    latex_engine: xelatex
    citation_pa... (etc.)

Does this work?

from oxforddown.

before input, Japanese characters got an

Can you confirm that you used exactly the same indentation as in my example above? It seems like this is just a parsing error of the YAML header. So, for example, you must put two spaces before " - \usepackage{xeCJK}".

As a starting point, try creating a new, R Markdown file that contains only the following, and knit it:

Can you confirm that this works?

I did a new RMarkdown with only 4 lines and put two spaces before " -\usepackage{xeCJK} then showed the following;

Can you show me the content of the entire R Markdown file you created, and I'll try to reproduce the error?

No, I meant can you confirm that you put only this content in a brand-new R Markdown file in a brand-new project?

So forgetting everything about oxforddown for a minute, are you normally able to use Japanese characters in R Markdown documents and output to PDF without any issues?
