# Japanese quotation marks do not display as full-width

When I use Japanese quotation marks at the start of a line, the whitespace at the beginning of the character seems to get cut off, moving the quotation mark half a space forward. This puts the text out of alignment when it should look like its aligned to a grid.

\documentclass{article}
\usepackage{xeCJK}
\begin{document}
\begin{enumerate}
\item
「あああああああああああああ」

あああああああああああああ。

「あああああああああああああ」

あああああああああああああ。
\end{enumerate}
\end{document}


Is there any way to force the quotation marks to display properly at their full-width without trimming the whitespace?

I do not know why this is, except that it seems like it's the kind of thing that is intended so as not to leave a space at the beginning of a line. But you can work around it by inserting a \strut before the opening bracket:

\documentclass{article}
\usepackage{xeCJK}
\begin{document}
\begin{enumerate}
\item \strut「あああああああああああああ」

あああああああああああああ。

\strut「あああああああああああああ」

あああああああああああああ。
\end{enumerate}
\end{document}


An alternative is to insert a half width space in your second lines:

\documentclass{article}
\usepackage{xeCJK}
\newlength{\cjktextsize}
\makeatletter
\newcommand{\cjkhalfspace}{%
\setlength{\cjktextsize}{\f@size pt}%
\hspace*{0.5\cjktextsize}}
\makeatother
\begin{document}
\begin{enumerate}
\item「あああああああああああああ」

\cjkhalfspace あああああああああああああ。

「あああああああああああああ」

\cjkhalfspace あああああああああああああ。
\end{enumerate}
\end{document}
