% \section{Font encodings}
%
% This section of the kernel contains commands for declaring
% encoding-specific
% commands, such as accents. It also contains the code for some of
% the encoding files, including |omlenc.def|,
% |omsenc.def|, |t1enc.def| and |ot1enc.def| files, which define
% the |OLM|,
% |OMS|, |T1| and |OT1| encodings, and the |fontenc| package
% for selecting encodings.
%
% The |fontenc| package has options for encodings, of which the
% last option is the default encoding. For example, to use the
% |OT2|, |OT3| and |T1| encodings, with |T1| as the default, you
% say:
%\begin{verbatim}
% \usepackage[OT2,OT3,T1]{fontenc}
%\end{verbatim}
% The standard kernel set-up loads font encoding files and selects
% an encoding as follows.
%\begin{verbatim}
% \input {omlenc.def}
% \input {t1enc.def}
% \input {ot1enc.def}
% \input {omsenc.def}
% \fontencoding{OT1}
%\end{verbatim}
% Note that the files in the standard |inputenc| package depend on
% this behaviour of the kernel.
%
% The syntax for declaring encoding-specific commands is:
% \begin{quote}
% |\DeclareTextCommand{|^^A
% \meta{command}|}{|^^A
% \meta{encoding}|}|\\\hspace*{\fill}|[|^^A
% \meta{number}|][|^^A
% \meta{default}|]{|^^A
% \meta{commands}|}|
% \end{quote}
% This command is like |\newcommand|, except that it defines a
% command which is specific to one encoding. The resulting command
% is always robust, even if its definition is fragile. For example,
% the definition of |\l| in the |OT1| encoding is:
%\begin{verbatim}
% \DeclareTextCommand{\l}{OT1}{{\@xxxii l}}
%\end{verbatim}
% |\DeclareTextCommand| takes the same optional arguments as
% |\newcommand|.
% \begin{quote}
% |\ProvideTextCommand{|^^A
% \meta{command}|}{|^^A
% \meta{encoding}|}|\\\hspace*{\fill}|[|^^A
% \meta{number}|][|^^A
% \meta{default}|]{|^^A
% \meta{commands}|}|
% \end{quote}
% This acts like |\DeclareTextCommand|, but does nothing if the
% command is already defined.
% \begin{quote}
% |\DeclareTextSymbol{|^^A
% \meta{command}|}{|^^A
% \meta{encoding}|}{|^^A
% \meta{slot}|}|
% \end{quote}
% This command defines a text symbol, with a particular slot in that
% encoding. The commands:
% \changes{v1.9h}{1997/12/17}{Example corrected, braces removed.}
%\begin{verbatim}
% \DeclareTextSymbol{\ss}{OT1}{25}
% \DeclareTextCommand{\ss}{OT1}{\char25 }
%\end{verbatim}
% have the same effect, but the |\DeclareTextSymbol| is faster.
% \begin{quote}
% |\DeclareTextAccent{|^^A
% \meta{command}|}{|^^A
% \meta{encoding}|}{|^^A
% \meta{slot}|}|
% \end{quote}
% \changes{v1.8e}{1996/11/23}{Corrected description}
% \changes{v1.9k}{1997/12/31}{Further correction}
% This command declares a text accent. The commands:
%\begin{verbatim}
% \DeclareTextAccent{\"}{OT1}{127}
% \DeclareTextCommand{\"}{OT1}{\add@accent {127}}
%\end{verbatim}
% have the same effect.
% \changes{v1.8c}{1996/10/27}
% {Corrected syntax descriptions}
% \begin{quote}
% |\DeclareTextComposite{|^^A
% \meta{command}|}|\\\hspace*{\fill}|{|^^A
% \meta{encoding}|}{|^^A
% \meta{argument}|}{|^^A
% \meta{slot}|}|
% \end{quote}
% This command declares a composite letter, for example in the |T1|
% encoding |\'{a}| is slot 225, which is declared by:
%\begin{verbatim}
% \DeclareTextComposite{\'}{T1}{a}{225}
%\end{verbatim}
% \changes{v1.8e}{1996/11/23}
% {Corrected description}
% The \emph{command} will normally have been declared with
% |\DeclareTextAccent|, or as a one-argument |\DeclareTextCommand|.
%
% |\DeclareTextComposite| is the most common example of using
% the more general declaration
% |\DeclareTextCompositeCommand|, which can define a composite
% to be an arbitrary piece of text.
% \begin{quote}
% |\DeclareTextCompositeCommand{|^^A
% \meta{command}|}|\\\hspace*{\fill}|{|^^A
% \meta{encoding}|}{|^^A
% \meta{argument}|}{|^^A
% \meta{text}|}|
% \end{quote}
% For example, in the OT1 encoding \r A has a hand-crafted
% defintion this is declared as follows
%\begin{verbatim}
% \DeclareTextCompositeCommand{\r}{OT1}{A}
% {\leavevmode\setbox\z@\hbox{h}\dimen@\ht\z@\advance\dimen@-1ex%
% \rlap{\raise.67\dimen@\hbox{\char23}}A}
%\end{verbatim}
% \changes{v1.8e}{1996/11/23}
% {Corrected description}
% The \emph{command} will normally have been declared with
% |\DeclareTextAccent|, or as a one-argument |\DeclareTextCommand|.
%
% The commands defined using the above declarations can be used in two
% ways. Normally they are used by just calling the command in the
% appropriate encoding, for example |\ss|. However, sometimes you
% may wish to use a command in an encoding where it is not defined.
% If the command has no arguments, then you can use it in another
% encoding by calling |\UseTextSymbol|:
% \begin{quote}
% |\UseTextSymbol{|^^A
% \meta{encoding}|}{|^^A
% \meta{command}|}|
% \end{quote}
%
% \changes{v1.9e}{1997/08/05}{Corrected order of arguments in
% \cs{UseTextSymbol} example.}
% For example, |\UseTextSymbol{OT1}{\ss}| has the same effect as:
%\begin{verbatim}
% {\fontencoding{OT1}\selectfont\ss}
%\end{verbatim}
% If the command has one argument then you can use it in another
% encoding by calling
% |\UseTextAccent|:
% \begin{quote}
% |\UseTextAccent{|^^A
% \meta{encoding}|}{|^^A
% \meta{command}|}{|^^A
% \meta{text}|}|
% \end{quote}
% For example, if the current encoding is |OT2| then
% |\UseTextAccent{OT1}{\'}{a}| has the same effect as:
%\begin{verbatim}
% {\fontencoding{OT1}\selectfont\'{\fontencoding{OT2}\selectfont a}}
%\end{verbatim}
% \changes{v1.8e}{1996/11/23}
% {Extended description}
% You can also declare a default definition for a text command, which
% will be used if the current encoding has no appropriate definition.
% Such use will also set the definition for this command in the
% current encoding to equal this default definition; this makes
% subsequent uses of the command much faster.
% \begin{quote}
% |\DeclareTextCommandDefault{|^^A
% \meta{command}|}{|^^A
% \meta{definition}|}|
% \end{quote}
% For example, the default definition of the command
% |\textonequarter| (which produces the fraction $\frac14$) could be
% built using math mode:
%\begin{verbatim}
% \DeclareTextCommandDefault{\textonequarter}{\ensuremath {\frac14}}
%\end{verbatim}
% There is a matching |\Provide| command which will not override an
% existing default definition:
% \begin{quote}
% |\ProvideTextCommandDefault{|^^A
% \meta{command}|}{|^^A
% \meta{definition}|}|
% \end{quote}
% The most common use for these commands is to use symbols from
% other encodings, so there are some optimizations provided:
% \begin{quote}
% |\DeclareTextSymbolDefault{|^^A
% \meta{command}|}|^^A
% \meta{encoding}|}|\\
% |\DeclareTextAccentDefault{|^^A
% \meta{command}|}|^^A
% \meta{encoding}|}|
% \end{quote}
% are short for:
% \begin{quote}
% |\DeclareTextCommandDefault{|^^A
% \meta{command}|}|\\\hspace*{\fill}^^A
% |{\UseTextSymbol{|^^A
% \meta{encoding}|}{|\meta{command}|}}| \\
% |\DeclareTextCommandDefault[1]{|^^A
% \meta{command}|}|\\\hspace*{\fill}^^A
% |{\UseTextAccent{|^^A
% \meta{encoding}|}{|\meta{command}|}{#1}}|
% \end{quote}
% For example, to make |OT1| the default encoding for |\ss| and
% |\'| you say:
%\begin{verbatim}
% \DeclareTextSymbolDefault{\ss}{OT1}
% \DeclareTextAccentDefault{\'}{OT1}
%\end{verbatim}
% Note that you can use these commands on any zero- or one-argument
% commands declared with |\DeclareText*| or |\ProvideText*|, not
% just those defined using |\DeclareTextSymbol| or
% |\DeclareTextAccent|.
%
% \subsection{Removing encoding-specific commands}\label{sec:removeencspec}
%
% \changes{v1.9o}{1998/03/20}{Documentation added for pr/2783}
%
% In some cases encoding definitions are given to provide some limited
% support since nothing better is available, for example, the definition
% for |\textdollar| in \texttt{OT1} is a hack since \$ and \pounds{}
% actually share the same slot in this encoding. Thus if such a glyph
% becomes available in a different encoding (e.g., \texttt{TS1}) one would
% like to get rid of the flacky one and make the default definition point
% to the new encoding. In such a case defining
%\begin{verbatim}
% \DeclareTextSymbol{\textdollar}{TS1}{36}
% \DeclareTextSymbolDefault{\textdollar}{TS1}
%\end{verbatim}
% is not enough since if typesetting in \texttt{OT1} \LaTeX{} will still find
% the encoding specific-definition for \texttt{OT1} and therefore ignore the
% new default.
% Therefore to ensure that in this case the \texttt{TS1} version is used
% we have to remove the \texttt{OT1} declaration:
%\begin{verbatim}
% \UndeclareTextCommand{\textdollar}{OT1}
%\end{verbatim}
%
% Since the \$ sign is a proper glyph in the \texttt{T1} encoding there is
% no point removing its definition and forcing \LaTeX{} to pick up the
% \texttt{TS1} version if typesetting in this encoding. However, assume
% you want to use the variant dollar sign, i.e., \textdollaroldstyle{}
% for your dollars. In that case you have to get rid of the \texttt{T1}
% declaration as well, e.g., the following could would do that for you:
%\begin{verbatim}
% \UndeclareTextCommand{\textdollar}{OT1}
% \UndeclareTextCommand{\textdollar} {T1}
% \DeclareTextCommandDefault{\textdollar}
% {\UseTextSymbol{TS1}\textdollaroldstyle}
%\end{verbatim}
%
% \subsection{The order of declarations}\label{sec:orderofdecls}
%
% \changes{v1.9o}{1998/03/20}{Documentation added about order of decls}
%
% If an encoding-specific command is defined for more than one encoding,
% then it will execute fastest in the encoding in which it was defined
% last since its top-level definition will be set up to execute in that
% encoding without any overhead.
%
% For this reason the file \texttt{fonttext.ltx} currently first loads
% the definitions for the \texttt{T1} encoding and then those for the
% \texttt{OT1} encoding so that typesetting in \texttt{OT1} is optimized
% since that is (still) the default. However, when \texttt{T1} is explicitly
% requested (via |\usepackage[T1]{fontenc}|) the top-level definitions
% are automatically changed to favor \texttt{T1} since its declarations are
% reloaded in the process.
%
% For the same reason default declarations should never come last since
% they are implemented as a special encoding themselves (with the name |?|).
% Specifying them last would simply mean to make those encoding-specific
% commands equally inefficient in all encodings. Therefore the
% \texttt{textcomp} package, for example, first sets up all defaults to point
% to \texttt{TS1} and then declares the commands in the \texttt{TS1} encoding.
%
%
% \StopEventually{}

% The sneaky bit in all this is what |\T1-cmd \foo \T1\foo| does.
% There are five possibilities, depending on the current values of
% |\protect|, |\cf@encoding| and |\ifmmode|:
% \begin{itemize}
% \item If |\protect| is |\@typeset@protect| and |\cf@encoding| is
% |T1|, then we execute |\T1\foo|. This should be the normal
% behaviour, and is optimized for speed.
% \item If |\protect| is |\@typeset@protect|, |\cf@encoding| is
% (say) |OT1|, and |\OT1\foo| is defined, then we execute
% |\OT1\foo|.
% \item If |\protect| is |\@typeset@protect|, |\cf@encoding| is
% (say) |OT1|, we're in text mode,
% and |\OT1\foo| is undefined, then we define
% |\OT1\foo| to be the default value of |\foo|, and execute
% |\OT1\foo|.
% \item If |\protect| is |\@typeset@protect|, |\cf@encoding| is
% (say) |OT1|, we're in math mode,
% and |\OT1\foo| is undefined, then we execute the default value
% of |\foo|. (This is necessary so that things like
% |$X_\copyright$| work properly.)
% \item If |\protect| is not |\@typeset@protect| then we execute
% |\noexpand\foo|. For example, if we are writing to a file,
% then this results in |\foo| being written. If we are in a
% |\mark|, then |\foo| will be put in the mark---since |\foo| is
% robust, it will then survive all the things which may happen
% to it whilst it's a |\mark|.
% \end{itemize}
% So after all that, we will either execute the appropriate
% definition of |\foo| for the current encoding, or we will execute
% |\noexpand\foo|.
%
% The default value of |\foo| is |\?\foo| if it is defined, and an
% error message otherwise.
%
% When the encoding is changed from |T1| to |OT1|, |\T1-cmd| is

% This all works because:

% expands to
% |\\T1\foo-A| if |\\T1\foo-A| has been defined, and |{...}|
% otherwise.
%
% Note that |\@text@composite| grabs the first token of the
% argument and puts just that in the
% csname. This is so that |\'{\textit{e}}| will work---it checks
% whether |\\T1\'-\textit| is defined (which presumably it isn't)
% and so expands to |{\accent 1 \textit{e}}|.
%
% This trick won't always work, for example |\'{{\itshape e}}| will
% expand to (with spaces added for clarity):
%\begin{verbatim}
% \csname \string \T1\' - \string {\itshape e} \@empty \endcsname
%\end{verbatim}
% which will die pretty horribly. Unfortunately there's not much
% can be done about this if we're going to use |\csname| lookups as a
% fast way of accessing composites.
%
% This has an unfortunate `misfeature' though, which is that in
% the T1 encoding, |\'{aa}| produces \'a. This is not the expected
% behaviour, and should perhaps be fixed if the fix doesn't affect
% performance too badly.
%
% Finally, it's worth noting that the |\@empty| is used in
% |\@text@composite| so that accents will work even when the
% argument is empty. If you say |\'{}| then this looks up
% |\\T1\'-\@empty|, which ought to be |\relax|, and so all is well.
% If we didn't include the |\@empty|, then |\'{}| would expand to:
%\begin{verbatim}
% \csname \string \T1\' - \string \endcsname

% rest of the document would be put inside the |\csname|. This

% names (like |\guillemotleft| and |\quotedblbase|). Unfortunately,
% this naming scheme won't work for all glyphs, since some names (like
% |\space|) are already used, and some (like |\endash|) are very
% likely to be defined by users. So we're now using the naming scheme
% of |\text| followed by the Adobe name, (like |\textendash| and

% so we're using the names used by fontinst for those (like

% This file now also contains some packages that provide access to
% the more specialised encodings.
%
% This one is for the |TS1| encoding which contains text symbols
% for use with the |T1|-encoded text fonts. It therefore first
% inputs the file |TS1enc.def| and then sets (or resets) the
% defaults for the symbols it contains. The result of this is that
% when one of these symbols is accessed and the current encoding
% does not provide it, the symbol will be supplied by a silent,
% local change to this encoding.

% Now having the new glyphs available we also want to make sure
% that they are used. For most cases this will automatically happen
% but for some glyphs there are inferior definitions already known
% to \LaTeX{} which will prevent the usage of the \texttt{TS1}
% versions (see section~\ref{sec:removeencspec} above). So we better
% get rid of them:
% \changes{v1.9o}{1998/03/20}{Added various \cs{UndeclareTextCommand}
% declarations for pr/2783}
% \begin{macrocode}
\UndeclareTextCommand{\textsterling}{OT1}

% From the \texttt{T1} encoding there are two candidates for removal:
% \textperthousand{} and \textpertenthousand{} since there are both
% constructed from \% followed by a tiny `{\fontencoding{T1}\selectfont
% \char 24}' rather than being a single glyph. The problem with this
% approach is that in PostScript fonts this small zero is usually not
% available resulting in \%\rule{3pt}{3pt} rather than
% \textperthousand{} while the real glyph (at least for
% |\textperthousand|) is available in the PostScript version of
% \texttt{TS1}. So for the moment we compromise by removing the
% \texttt{T1} declaration for |\textperthousand| but keeping the one
% for |\textpertenthousand|. This will have the effect that with
% Computer Modern fonts everything will come out (although
% \textperthousand{} and \textpertenthousand{} are not taken from the
% same physical font) and with PostScript fonts \textperthousand{} will
% come out correctly while \textpertenthousand{} will most likely look
% like \%\rule{6pt}{3pt} --- which is probably an improvent over just
% getting a single `\rule{3pt}{3pt}' to indicate a fully missing glyph
% which would happen if we would also undeclare |\textpertenthousand|.
