This is the file commands.doc of the CJK macro package ver. 4.2.0
(13-Dec-1998).

Here is a table of all commands of CJK.


\begin{CJK}[<fontencoding>]{<encoding>}{<family>}
...
\end{CJK}

        This starts a CJK environment.

        Possible values for <encoding> are:
            `Bg5', `GB', `GBt', `JIS', `SJIS', `KS', `UTF8';

            [`CNS1'-`CNS7', `CEFX', `CEFY' are also possible but make no
             sense. These are used with CEF and Mule. The same holds for
             `JIS2'.]

        Possible values for <fontencoding> are (default is empty):
            `pmC' (for Bg5, GB, GBt, JIS, KS), `dnp' and `wn' (for JIS),
            `HL' (for KS). 

        Possible values for <family> are defined in the FD files which must
        be configured for the available fonts. If empty, the default value
        (`mj' for KS encoding, `song' for the rest) will be used.

        Families can be changed with \CJKencfamily on a per-encoding base
        and with \CJKfamily for all encodings. \CJKfamily overrides
        \CJKencfamily; to have \CJKencfamily active you must assure that the
        `family' parameter of the CJK environment is empty or that
        \CJKfamily is defined as empty (inside the environment).

        Fontencodings can be changed on a per-encoding base with
        \CJKfontenc; \CJKenc will always use the specified fontencoding.

        The hook \CJKhook will be called on initializing the environment
        (used by cjk-enc.el).
        
        Newlines and spaces after a CJK character will be retained. If you
        want to suppress a newline, finish the line with `%'.

        See also \CJKspace and \CJKnospace.


\begin{CJK*}[<fontencoding>]{<encoding>}{<family>}
...
\end{CJK*}

        The same as the CJK environment except that newlines and spaces
        after a CJK character are swallowed. If you want a space after a CJK
        character you must protect it (e.g. use `\ ').

        See also \CJKspace and \CJKnospace.


Text containing CJK characters should start with a fresh line (in the source
file, not in the output) because TeX has already read in the characters of
the current line as non-active characters.

You can stack CJK environments (i.e. saying \begin{CJK}...\end{CJK} again
inside of a CJK environment) if you have not set the `global' package
option, but it is possible that TeX's `save size' will overflow. Use
\CJKenc, \CJKfontenc, \CJKfamily, and \CJKencfamily instead. See CJK.doc for
CJK package options which modify the scope of the CJK environment.

To have different encodings/families on the same input line you must use
\CJKenc, \CJKfontenc, \CJKfamily, and/or \CJKencfamily.

If you use cjk-enc.el with Mule, you should NOT open a CJK (or CJK*)
environment! It will be done automatically. See cjk-enc.doc for details.


==============================================================================


The following commands are defined (or make sense) only inside of a CJK or
CJK* environment (except \CJKbold, \CJKnormal, \CJKencfamily, \CJKfontenc,
\CJKhangul, \CJKhanja, and \CJKaddEncHook).


\CJKcaption{<caption>}  Load <caption>.cap, a language/encoding specific
                        caption file. You will need the SCRIPT style files
                        of the koma-script package to fully use them (see
                        CJK.doc for details).

                        If in preprocessed mode <caption>.cpx will be loaded
                        instead.

        Example:

                \begin{CJK*}{Bg5}{song}
                \CJKcaption{Bg5}
                ...
                \end{CJK*}


\CJKchar[<enc>]{<byte1>}{<byte2>}
                        Insert a CJK character literally. <byte1> and
                        <byte2> are the first and second byte of the CJK
                        character (in the selected encoding), the optional
                        parameter selects the encoding. You can use decimal,
                        hexadecimal, or octal notation. <byte1> and <byte2>
                        can be both in 7bit or 8bit (GL or GR)
                        representation. To select Unicode characters you
                        must specify `UTF8' encoding (but enter real Unicode
                        values).

        Examples:

                \CJKchar[Bg5]{217}{223}
                \CJKchar[CNS1]{"57}{"4C}
                \CJKchar[UTF8]{"0D9}{"04F}


\CJKenc{<encoding>}     Change encoding. Contrary to \begin{CJK}{...}{...}
                        it's not necessary to start a new line after
                        \CJKenc. This command will always use the
                        fontencoding selected with \CJKfontenc.

                        \CJKenc will act globally if the `global' option is
                        set.

                        See fonts.doc for a mapping table between CJK
                        encoding names and the names of the FD files
                        finally used.

                        Use the macro \CJKaddEncHook to add commands which
                        should be executed when a certain encoding is
                        selected.
                        

\CJKfamily{<family>}    Change family for all encodings. This command
                        overrides \CJKencfamily; to reactivate \CJKencfamily
                        say `\CJKfamily{}'.

                        \CJKfamily will act globally if the `global' option
                        is set.


\CJKencfamily[<fontencoding>]{<encoding>}{<family>}
                        Change family for a certain encoding (and
                        fontencoding). Can be overridden with \CJKfamily.

                        The possible values of <family> are defined in the
                        encoding specific FD files.

                        This command makes sense outside of a CJK
                        environment; it will act globally if the `global'
                        option is set.


\CJKfontenc{<encoding>}{<fontencoding>} 
                        Change fontencoding for a certain encoding. If you
                        select an encoding with \CJKenc, the fontencoding
                        specified with \CJKfontenc for this encoding will be
                        chosen.

                        This command makes sense outside of a CJK
                        environment; it will act globally if the `global'
                        option is set.

        Example:

            \CJKencfamily{GBt}{hei}
            \CJKfontenc{JIS}{dnp}

            \begin{CJK*}{Bg5}{fs}                   %   this is equal to
                                                    %   \begin{CJK*}{}{}
                                                    %   \CJKenc{Bg5}
                                                    %   \CJKfamily{fs}

            ... Text in Bg5 fangsong ...            %   c00fs.fd used
            \CJKenc{GB} ... Text in GB fangsong ... %   c10fs.fd used
            \CJKfamily{kai} ... Text in GB kai ...  %   c10kai.fd used
            \CJKenc{JIS} ... Text in JISdnp kai ... %   c42kai.fd used
            \CJKfamily{}%
            \CJKenc{GBt} ... Text in GBt hei ...    %   c20hei.fd used
            \end{CJK*}


\CJKkern                To prevent a line break before a CJK character, say
                        \CJKkern. This command suppresses the insertion of
                        \CJKglue before the CJK character.


\CJKglue                If you get overfull \hbox'es caused by CJK
                        characters, try to increase \CJKglue. It defines the
                        glue between CJK characters; the default definition
                        is

                \newcommand{\CJKglue}{\hskip 0pt plus 0.08\baselineskip}  .

                        \CJKglue will be inserted by CJK between Chinese
                        characters (except punctuation characters as defined
                        in the punctuation tables; see CJK.enc). You should
                        separate non-Chinese text from CJK characters with
                        spaces to enable hyphenation. Or you can say


\CJKtilde               This command changes the definition of the active
                        `~' character from an unbreakable space to

                \def~{\hspace{0.25em plus 0.125em minus 0.08em}}        .


\nbs                    The original meaning of `~' is preserved within \nbs,
                        a shorthand for the LaTeX command \nobreakspace.
\standardtilde          To return to the original definition of `~' use this
                        command.


\CJKspace
\CJKnospace             Switch from CJK to CJK* `mode' (\CJKnospace) or
                        vice versa (\CJKspace).


\CJKhanja
\CJKhangul              \CJKhanja deactivates the use of C61 font encoding
                        for hangul characters, all fonts used have C60 font
                        encoding; \CJKhangul is the opposite command. The
                        default is C61 for hangul.

                        Archaic hangul elements (KS 0xA4D5-0xA4FE) and the
                        character KS 0xA4D4 are only accessible if \CJKhanja
                        is active.

                        Both commands will act globally if the `global'
                        option is set.

                        These commands make sense outside of a CJK
                        environment.


\CJKtolerance           If you get overfull \hbox'es caused by KS
                        characters, try to increase \CJKtolerance. The
                        default definition is

                \newcommand{\CJKtolerance}{400}  .

                        Increasing \emergencystretch may help also.


\CJKuppercase           In Big 5 and SJIS environments the LaTeX command
                        \MakeUppercase is disabled, otherwise wrong CJK
                        characters would be selected. In the unlikely case
                        that you really need \MakeUppercase, use
                        \CJKuppercase instead.

                        This restriction does not exist for preprocessed CJK
                        files, i.e., files processed with Bg5conv, SJISconv,
                        CEF5conv, CEFSconv, or cjk-enc.el, thus
                        \CJKuppercase will not be defined in these cases.

                        \CJKuppercase will act globally if the `global'
                        option is set.


\begin{Bg5text}
...
/end(Bg5text)

\begin{SJIStext}
...
/end(SJIStext)          Enable the use of Big 5/SJIS encoded characters
                        which contain `\', `{', and `}' as second bytes. See
                        CJK.doc for a complete discussion. You will need
                        these environments only in rare cases where
                        Bg5conv/SJISconv or cjk-enc.el can't be used.


\Unicode{<byte1>}{<byte2>}
                        Insert a Unicode character literally. <byte1> and
                        <byte2> are the first and second byte of the Unicode
                        character. You can use decimal, hexadecimal, or octal
                        notation. This command can only be used within UTF 8
                        encoding. In all other encodings you must say
                        \CJKchar[UTF8]{<byte1>}{<byte2>} instead.


\CJKCJKchar
\CJKhangulchar
\CJKlatinchar           These commands control the handling of
                        intercharacter glue. Only defined for UTF8 encoding.
                        \CJKCJKchar selects CJK style (using \CJKglue),
                        \CJKhangulchar selects hangul style (using
                        \CJKtolerance) and \CJKlatinchar uses none. Default
                        is \CJKCJKchar.

                        Only 3-byte UTF 8 encoded characters (i.e., Unicode
                        characters in the range 0x800-0xFFFF) are affected;
                        two-byte encoded characters will be handled as
                        ordinary characters (i.e., as if \CJKlatinchar were
                        set).


\CJKbold
\CJKnormal              These commands will set and unset the \ifCJK@bold@
                        flag. If set, boldface will be emulated.

                        Both commands are intended to appear in
                        \DeclareFontShape commands (usually in FD files);
                        see fonts.doc for further details.

\CJKsymbol              The CJK package uses this command instead of \symbol
                        to print a CJK character; it honours the
                        \ifCJK@bold@ flag: if set, boldface will be emulated
                        by printing the character three times with slight
                        horizontal offsets. There should be hardly a reason
                        to ever use this command explicitly.
\CJKsymbols             A similar command specific to HLaTeX font support.
                        It takes two characters which are then mapped to the
                        final glyph using TeX's ligature mechanism.

\CJKboldshift           The horizontal shift used for imitating bold
                        fonts. Redifine this macro if the default value of
                        0.015em is not satisfying.

\CJKaddEncHook{<encoding>}{<body>}
                        This macro is primarily intended for packages. Use
                        it to append the code in <body> to a hook for
                        <encoding> which is executed each time <encoding> is
                        selected. For an example see CJKnumber.sty .
