# Korean

## Introduction

LaTeX supports many worldwide languages by means of special packages. This article explains how to import and use packages to typeset documents containing Korean text. A list of Korean typefaces available on Overleaf can be found [here](/latex/questions-and-answers/85-which-otf-or-ttf-fonts-are-supported-via-fontspec.md#korean).

### Example using Google Noto CJK fonts

We can use the `xeCJK` package, which requires the XeLaTeX compiler, to typeset some Korean using the [Noto CJK fonts](https://www.google.com/get/noto/help/cjk/) installed on Overleaf:

```latex
\documentclass{article}
\usepackage{xeCJK}
\setmainfont{Noto Serif}
\setCJKmainfont{Noto Serif CJK KR}
\setCJKsansfont{Noto Sans CJK KR}
\setCJKmonofont{Noto Sans Mono CJK KR}
\begin{document}
\section{소개}
전체 문서에 대한 기본 정보를 소개 단락.

\begin{verbatim}
그것은 간격 방법을 참조 그대로 글꼴을 테스트
\end{verbatim}

Latin characters are also allowed.
\end{document}
```

This example produces the following output:

![Basic example of typesetting Korean](/files/VHHco23xGu7oY6prTiob)

In the above example four different different fonts are declared:

* `\setmainfont{Noto Serif}`: Uses the Noto Serif font for text with Latin characters.
* `\setCJKmainfont{Noto Serif CJK KR}`: Sets the font `Noto Serif CJK KR` to be used as the main font.
* `\setCJKsansfont{Noto Sans CJK KR}`: Just as the previous command, this uses `Noto Sans CJK KR` for document elements to be typeset in a sans serif font.
* `\setCJKmonofont{Noto Sans Mono CJK KR}`: Uses the `Noto Sans Mono CJK KR` font for document elements that require a monospace font; for instance, within the `verbatim` environment.

### Example using Noto fonts and different font weights

Because the `xeCJK` package uses `fontspec` the usual LaTeX font style, family and weight selection commands, such as `\ttfamily`, `\bfseries` and `\textsf` continue to work, as shown in the following example:

```latex
\documentclass{article}
\usepackage{xeCJK}
\setmainfont{Noto Serif}
\setCJKmainfont{Noto Serif CJK KR}
\setCJKsansfont{Noto Sans CJK KR}
\setCJKmonofont{Noto Sans Mono CJK KR}
\begin{document}

\vspace*{10pt}

\noindent And of course, Latin characters are also allowed in \textbf{bold} or \textit{italics}.
\end{document}
```

## Example using xeCJK with fonts loaded into your project

The following example uses fonts, `UnGungseo.ttf` and `gulim.ttf`, uploaded into the Overleaf project.

```latex
\documentclass{article}
\usepackage{xeCJK}

\setmainfont{Noto Serif}
\setCJKmainfont{UnGungseo.ttf}
\setCJKsansfont{UnGungseo.ttf}
\setCJKmonofont{gulim.ttf}

This example produces the following output:

![Typestting Korean using pdfTeX](/files/S5GGX5Gw6saaTFfzGgA5)

## Typesetting Korean documents with pdfLaTeX

If your workflow means you *have* to use pdfLaTeX, and cannot use XeLaTeX, you can use the `CJKutf8` package with pdfLaTeX. Here is an example:

```latex
\documentclass{article}
\usepackage{CJKutf8}
\begin{document}
\begin{CJK}{UTF8}{mj}
 전체 문서에 대한 기본 정보를 소개 단락.

 \begin{verbatim}
 그것은 간격 방법을 참조 그대로 글꼴을 테스트
 \end{verbatim}
\end{CJK}

Latin characters are also allowed.
\end{document}
```

This example produces the following output:

![Typesetting Korean using CJKuft8](/files/aqhvp827w1qLinqKIXL5)

Note that in order to type Korean text you must use the `CJK` environment:

`\begin{CJK}{UTF8}{mj}`will start a `CJK` environment, the first parameter passed to the environment declaration is the text encoding. Use only `UTF8` on Overleaf, since all text files on Overleaf are UTF8. The second parameter is the font family to be used: use `mj` for Korean.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/languages/12-korean.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
