This is the file commands.txt of the CJK macro package ver. 4.8.5
(16-Oct-2021).

Here is a list of all commands of CJK.


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

        This starts a CJK environment.

        Possible values for <encoding> are:
            `Bg5', `Bg5+', `GB', `GBt', `GBK', `JIS', `SJIS', `KS', `UTF8',
            `EUC-TW', `EUC-JP'.

            [`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:
            `' (empty, the default), `pmC' (for Bg5, GB, GBt, JIS, KS),
            `dnp' (for JIS and SJIS), `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) is 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).

        Font encodings can be changed on a per-encoding base with
        \CJKfontenc; \CJKenc always uses the specified font encoding.

        The hook \CJKhook is called on initializing the environment (used
        by cjk-enc.el and VTeX, for example).

        Newlines and spaces after a CJK character are 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) after activating a CJK environment 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' overflows. Use \CJKenc,
\CJKfontenc, \CJKfamily, and \CJKencfamily instead. See CJK.txt 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, you should NOT open a CJK (or CJK*) environment! It
is done automatically. See cjk-enc.txt for details.


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


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


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

                        <caption>.cpx is a preprocessed version of
                        <caption>.cap.

        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). If the
                        Unicode value is greater than U+FFFF, put the first
                        two bytes into the first argument, and the third byte
                        into the second one.


        Examples:

                \CJKchar[Bg5]{217}{223}
                \CJKchar[CNS1]{"57}{"4C}
                \CJKchar[UTF8]{"02D9}{"04F}


\CJKenc{<encoding>}     Change encoding. Contrary to \begin{CJK}{...}{...}
                        it is not necessary to start a new line after
                        \CJKenc. This command always uses the font encoding
                        selected with \CJKfontenc.

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

                        See fonts.txt 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 acts globally if the `global' option is
                        set.


\CJKencfamily[<fontencoding>]{<encoding>}{<family>}
                        Change family for a certain encoding (and
                        font encoding). 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 acts globally if the `global' option
                        is set.


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

                        This command makes sense outside of a CJK
                        environment; it acts 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*}


\CJKindent              The `classical' indentation for CJK documents is
                        exactly two ideographic spaces. \CJKindent sets
                        the paragraph indentation to this value, using
                        \parindent and the currently active CJK font.


\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. The default
                        definition is

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

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


\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).


\CJKverbatim            If the `verbatim' package is loaded it is possible
                        to improve the output automatically, namely, to
                        avoid breaking of overfull lines in a verbatim
                        environment. This command installs a hook to
                        suppress insertion of glue between CJK and Thai
                        glyphs.


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

                        These commands make sense outside of a CJK
                        environment.


\CJKhwkatakana
\CJKnohwkatakana        \CJKnohwkatakana deactivates the use of the C49
                        font encoding and maps half-width katakana
                        characters to full-width glyphs instead.
                        \CJKhwkatakana (the default) is the opposite
                        command.

                        Both commands act globally if the `global' option is
                        set; they have only effect for SJIS input encoding.

                        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.

                        This command makes sense outside of a CJK
                        environment.


\CJKuppercase           If Big 5, SJIS, Bg5+, or GBK characters are used
                        non-preprocessed, 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, extconv, or cjk-enc.el, thus
                        \CJKuppercase is not defined in these cases.

                        \CJKuppercase acts 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.txt for a complete discussion. You need these
                        environments only in rare cases where
                        bg5conv/sjisconv or cjk-enc.el can't be used.

\begin{Bg5+text}
...
/end(Bg5+text)

\begin{GBKtext}
...
/end(GBKtext)           Enable the use of Big 5+/GBK encoded characters
                        which contain `\', `{', and `}' as second bytes. See
                        CJK.txt for a complete discussion. You need these
                        environments only in rare cases where extconv can't
                        be used.


\Unicode{<byte1>}{<byte2>}
\Unicode{<byte1><byte2>}{<byte3>}
                        Insert a Unicode character literally. <byte1>,
                        <byte2>, and <byte3> are the first, second, and
                        third 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>} or
                        \CJKchar[UTF8]{<byte1><byte2>}{<byte3>} instead.


        Examples:

                \Unicode{"23}{"45}
                \Unicode{"25E}{"9A}

\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 is handled as ordinary
                        characters (i.e., as if \CJKlatinchar were set).


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

                        Both commands are intended to appear in
                        \DeclareFontShape commands only (usually in FD
                        files); see fonts.txt 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 is 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.
                        Redefine this macro if the default value of 0.015em
                        is not satisfying.

                        These commands make sense outside of a CJK
                        environment.


\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 CJKnumb.sty .
