+\maketitle
+
+The command \verb+\xspace+ of package \textsf{xspace}
+(included in \textsf{latex-tools} bundle)
+results in wrong interword spacing when followed by
+a Japanese character.
+The package \textsf{pxxspace} provides a patch for \textsf{xspace}
+to correct interword spacing with Japanese characters.
+
+This package is part of \textsf{platex-tools} bundle:
+\begin{verbatim}
+ https://github.com/aminophen/platex-tools
+\end{verbatim}

+
+\textsf{xspace}パッケージ(\textsf{latex-tools}バンドルの一つ)が
+提供する \verb+\xspace+ 命令は、その直後に和文文字を伴うときに
+その和文文字との間のスペーシングが正しくなりません。
+そこで、\textsf{pxxspace}パッケージを読み込めば
+和文文字との間のスペーシングが修正されます。
+
+以下に例を示します。
+\begin{verbatim}
+ % Sample code
+ \documentclass{article}
+ \usepackage{pxxspace}% or, \usepackage{xspace}
+ \newcommand\myTeX{\TeX\xspace}
+ \begin{document}
+ % ASCII-Kanji interword spacing should be 20pt.
+ % At the same time, no spacing before JP punctuations.
+ \xkanjiskip 20pt % visible
+ \myTeX is great!\par
+ \myTeX, it's awesome!\par
+ \myTeX は素晴らしい!\par
+ \myTeX、超スゴイ!\par
+ \end{document}
+\end{verbatim}
+
+\begin{quote}
+\begin{multicols}{2}

+ \long\def\TEST{%
+ \myTeX is great!\par
+ \myTeX, it's awesome!\par
+ \myTeX は素晴らしい!\par
+ \myTeX、超スゴイ!\par
+ }
+ % 正しいスペーシング:
+ Correct with \verb+\usepackage{pxxspace}+\par
+ \TEST
+ % 誤ったスペーシング:
