+The primitive \verb+\inhibitglue+ suppresses the insertion of \textbf{JAglue}.
+The following is an example, using a special JFM that there will be a glue between
+the beginning of a box and `あ', and also between `あ' and `ウ'.
+
+\begin{LTXexample}
+\jfont\g=psft:Ryumin-Light:jfm=test \g
+あウあ\inhibitglue{}ウ\inhibitglue\par
+あ\par\inhibitglue{}あ
+\par\inhibitglue\hrule{}あoff\inhibitglue ice
+\end{LTXexample}
+
+With the help of this example, we remark the specification of \verb+\inhibitglue+:
+\begin{itemize}
+\item The call of \verb+\inhibitglue+ in the (internal) vertical mode is
+ effective at the beginning of the next paragraph. This is realized
+ by hacking \verb+\everypar+.
+\item The call of \verb+\inhibitglue+ in the (restricted) horizontal
+ mode is only effective on the spot; does not get over boundary of
+ paragraphs. Moreover, \verb+\inhibitglue+ cancels ligatures and
+ kernings, as shown in line~4 of above example.
+\item The call of \verb+\inhibitglue+ in math mode is just ignored.
+\end{itemize}

+\label{ssub-nfsspat}
+As described in Subsection~\ref{ssec-ltx}, \LuaTeX-ja simply adopted
+\texttt{plfonts.dtx} in \pLaTeXe\ for the Japanese patch for NFSS2.
+For an convenience, we will describe
+commands which are not described in Subsection~\ref{ssub-chgfnt}.
+
+\begin{cslist}%
+\item[DeclareYokoKanjiEncoding\{<encoding>\}\{<text-settings>\}\{<math-settings>\}]
+In NFSS2 under \LuaTeX-ja, distinction between alphabetic font families
+ and Japanese font families is only made by its
+ encoding. For example, encodings OT1 and T1 are for
+ alphabetic font families, and a Japanese font family cannot
+ have these encodings. This command defines a new encoding
+ scheme for Japanese font family (in horizontal direction).
+
+\item[DeclareKanjiEncodingDefaults\{<text-settings>\}\{<math-settings>\}]
+\item[DeclareKanjiSubstitution\{<encoding>\}\{<family>\}\{<series>\}\{<shape>\}]
+\item[DeclareErrorKanjiFont\{<encoding>\}\{<family>\}\{<series>\}\{<shape>\}\{<size>\}]
+
+The above 3~commands are just the counterparts for \verb+DeclareFontEncodingDefaults+ and~others.
+
+\item[reDeclareMathAlphabet\{<unified-cmd>\}\{<al-cmd>\}\{<ja-cmd>\}]
+和文・欧文の数式用フォントファミリを一度に変更する命令を作成する.
+具体的には,欧文数式用フォントファミリ変更の命令<al-cmd>と,和文数式用フォ
+ ントファミリ変更の命令<ja-cmd>の2つを同時に行う命令として
+ <unified-cmd>を(再)定義する.実際の使用では<unified-cmd>と
+ <al-cmd>に同じものを指定する,すなわち,<al-cmd>に和文側も変
+ 更させるようにするのが一般的と思われる.
+
+本コマンドの使用については,\pLaTeX 配布中の\texttt{plfonts.dtx}に詳しく
+ 注意点が述べられているので,そちらを参照されたい.
+
+\item[DeclareRelationFont\{<ja-encoding>\}\{<ja-family>\}\{<ja-series>\}\{<ja-shape>\}\\
+ \hfill\{<al-encoding>\}\{<al-family>\}\{<al-series>\}\{<al-shape>\}]
+%<*en>
+This command sets the `accompanied' alphabetic font family (given by the latter 4~arguments)
+with respect to a Japanese font family given by the former 4~arguments.
+%</en>
+%<*ja>
+いわゆる「従属欧文」を設定するための命令である.前半の4引数で表される和文フォントファミリに対して,
+そのフォントに対応する「従属欧文」フォントファミリを後半の4引数により与える.
+%</ja>
+\item[SetRelationFont]
+This command is almost same as \verb+\DeclareRelationFont+, except that this command does a local
+assignment, where \verb+\DeclareRelationFont+ does a global assignment.
+\item[userelfont]
+Change current alphabetic font encoding/family/\dots\ to the `accompanied' alphabetic
+ font family with respect to current Japanese font family,
+ which was set by
+ \verb+\DeclareRelationFont+ or \verb+SetRelationFont+.
+Like \verb+\fontfamily+, \verb+\selectfont+ is required to take an effect.
+
+\item[adjustbaseline]
+...
+
+\item[fontfamily\{<family>\}]
+{\let\item\origitem
+As in \LaTeXe, this command changes current font family (alphabetic, Japanese,~\emph{or both})
+to <family>. Which family will be changed is determined as follows:
+\begin{itemize}
+\item Let current encoding scheme for Japanese fonts be
+ <ja-enc>. Current Japanese font family will be changed to
+ <family>, if one of the following two conditions is met:
+\begin{itemize}
+\item The family <fam> under the encoding <ja-enc> is already defined by
+ \verb+\DeclareKanijFamily+.
+\item A font definition named \texttt{<enc><ja-enc>.fd} (the file name is
+ all lowercase) exists.
+\end{itemize}
+\item Let current encoding scheme for Japanese fonts be
+ <al-enc>. For alphabetic font family, the criterion as above is used.
+\item There is a case which none of the above applies, that is, the font
+ family named <family> doesn't seem to be defined neither under the
+ encoding <ja-enc>, nor under <al-enc>.
+
+In this case, the default family for font substitution is used for
+ alphabetic and Japanese fonts. Note that current encoding will not
+ be set to <family>, unlike the original implementation in \LaTeX.
+\end{itemize}
+}
+\end{cslist}
+
+As closing this subsection, we shall introduce an example of
+\verb+SetRelationFont+ and \verb+\userelfont+:
+\begin{LTXexample}
+\gtfamily{}あいうabc
+\SetRelationFont{JY3}{gt}{m}{n}{OT1}{pag}{m}{n}
+\userelfont\selectfont{}あいうabc
+\end{LTXexample}

+This optional package supports typesetting characters in

+commands:
+\begin{list}{}{\def\makelabel{\ttfamily}\def\{{\char`\{}\def\}{\char`\}}}
+\item[\char92CID\{<number>\}]
+Typeset a character whose CID number is <number>.
+\item[\char92UTF\{<hex\_number>\}]
+Typeset a character whose character code is <hex\_number> (in hexadecimal).
+This command is similar to \verb+\char"+<hex\_number>,\ %"
