Setting whether inserting \Param{xkanjiskip} is allowed before/after a \textbf{JAchar} whose character code is <chr\_code>.
The followings are allowed for <mode>:
\begin{description}
\item[0, \texttt{inhibit}] Insertion of \Param{xkanjiskip} is inhibited before the character, nor after the character.
-\item[2, \texttt{preonly}] Insertion of \Param{xkanjiskip} is allowed before the character, but not after.
-\item[1, \texttt{postonly}] Insertion of \Param{xkanjiskip} is allowed after the character, but not before.
+\item[1, \texttt{preonly}] Insertion of \Param{xkanjiskip} is allowed before the character, but not after.
+\item[2, \texttt{postonly}] Insertion of \Param{xkanjiskip} is allowed after the character, but not before.
\item[3, \texttt{allow}] Insertion of \Param{xkanjiskip} is allowed before the character and after the character.
This is the default value.

+This parameter is similar to the \verb+\inhibitxspcode+ primitive of \pTeX, but not compatible with \verb+\inhibitxspcode+.
