Korean characters in article title

Question

I'm writing a paper in English and need to include a few characters in Korean in the body and title. I've read several other posts and managed to get the Hangul to show up inside the body, but I can't get them to show up inside the title. I am using pdflatex and have all of the necessary fonts installed.

Here's the minimum working example that shows the characters appearing in the body but not in the title on my system:

\documentclass[11pt]{article}

\usepackage[utf8x]{inputenc}
\usepackage[thai,english]{babel}
\addto\extrasthaicjk{\fontencoding{C90}\selectfont}

\makeatletter
\@namedef{opt@inputenc.sty}{utf8}
\makeatother
\usepackage{CJKutf8}

\newenvironment{Korean}{%
  \CJKfamily{mj}}{}

\title{
  Character does not show up here:
   \begin{CJK}{UTF8}{mj}\begin{Korean}시험\end{Korean}\end{CJK}
}

\begin{document}
\maketitle

It works here  \begin{CJK}{UTF8}{mj}\begin{Korean}시험\end{Korean}\end{CJK}    

\end{document}

I don't see any errors about the title, so I'm stuck on what to do. This is my first time including foreign script characters in a LaTeX, so any help would be much appreciated. Thanks!

In your original document, if you put your \title command after \begin{document} things work. However, if you don't load the inputenc package at all, things also work. I think this is a better solution. I've added the fontenc package to use the T1 encoding for the Latin text and removed the trick that @egreg mentions in his comment.

\documentclass[11pt]{article}

\usepackage[T1]{fontenc}
\usepackage[english]{babel}

\usepackage{CJKutf8}
\newcommand\textkorean[1]{%
  \begin{CJK}{UTF8}{mj}#1\end{CJK}}

\title{
   Character now shows up here:
   \textkorean{시험}
}
\begin{document}
\maketitle

It works here \textkorean{시험}

\end{document}
