-It is well-known that there is a patch |jlisting.sty| of the
- \emph{listings} package for p\LaTeXe. Generally speaking, it
- also can be used in \LuaTeX-ja. However, it seems to be that

- process of the \emph{listings} package; this is inconvinient
- when we use the \emph{showexpl} package.
+It is known for users of \pTeX that there is a patch |jlisting.sty| for

+
+There is another way to use characters above 256 with the
+ \emph{listings} package (described in\cite{apl}), however,
+ this method is not suitable for Japanese, since the number of
+ Japanese characters is very large. We hope that the
+ \emph{listings} package can cope with all characters above
+ 256.
