%
% This file contains the implementation for accessing the glyphs
% provided by the \texttt{TS1} encoding (Text Companion
% Encoding). This is now offered as part of the kernel and so the
% \texttt{textcomp} package which used to provide the definitions is
% now mainly needed for compatibility reasons (and doesn't do much any
% more).

%    Then switch to the math italic font. We don't change the current

%
%  \begin{macro}{\DeclareEncodingSubset}
%
%    The declaration takes 3 mandatory arguments: an \emph{encoding}
%    for which a subsetting is wanted (currently always \texttt{TS1},
%    and most likely forever), the \emph{font family} for which we
%    declare the subset and finally the \emph{subset} number, with a value between
%    \texttt{0} (all of the encoding is supported) and \texttt{9} (many
%    glyphs are missing).
%
%    For \texttt{TS1} the numbers have been chosen in a way that most
%    fonts can be fairly correctly categorized, but the default
%    settings are always conservative, that is they may claim that
%    less glyphs are supported than there actually are.
%
%    As these days many font families are set up to end in \texttt{-LF}
%    (lining figures), \texttt{-OsF} (oldstyle figures), etc.\ the
%    declaration supports a shortcut: if the \emph{font family} name
%    ends in \texttt{-*} then the star gets replaced by these common
%    ending, e.g.,
%\begin{verbatim}
% \DeclareEncodingSubset{TS1}{Alegreya-*}{2}
%\end{verbatim}
%    is the same as writing
%\begin{verbatim}
% \DeclareEncodingSubset{TS1}{Alegreya-LF}{2}
% \DeclareEncodingSubset{TS1}{Alegreya-OsF}{2}
% \DeclareEncodingSubset{TS1}{Alegreya-TLF}{2}
% \DeclareEncodingSubset{TS1}{Alegreya-TOsF}{2}
%\end{verbatim}
%    If only some are needed then one can define them individually but
%    in many cases all four are wanted, hence the shortcut.
%
%
%    The coding of the declaration has no error checking as it is
%    mostly for internal use.

% \begin{macro}{\CheckEncodingSubset}
%    The command |\CheckEncodingSubset| will check if the current font
%    family has the right encoding subset to typeset a certain
%    command. It takes five arguments as follows:
%    first argument is either |\UseTextSymbol|, |\UseTextAccent|
%    depending on whether or not the symbol is a text symbol or a text
%    accent.

%    The second argument is the encoding from which this symbol should
%    be fetched.
%
%    The third argument is either a fake accessor command or an error
%    message. the code in that argument (if ever executed) receives
%    two arguments: |#2| and |#5| of |\CheckEncodingSubset|.
%
%    Argument four is the subset encoding id to test against: if this
%    value is higher than the subset id of the current font family
%    then we typeset the symbol, i.e., execute |#1{#2}#5| otherwise
%    it runs |#3#5|, e.g., to produce an error message or fake the
%    glyph somehow.
%
%    Argument five is the symbol or accent command that is being
%    checked.
%
%    For usage examples see definitions below.

%

% \section{Sub-encodings}
%
%    Here are the default definitions for the \texttt{TS1} symbols.
%    First those that we assume are always available if a font
%    implements \texttt{TS1}.
%
%    \begin{macrocode}
\DeclareTextSymbolDefault{\textdollar}{TS1}
\UndeclareTextCommand{\textdollar}{OT1}  % don't use the OT1 def any longer
%    \end{macrocode}
%
%    \begin{macrocode}
\DeclareTextSymbolDefault{\textsterling}{TS1}
\UndeclareTextCommand{\textsterling}{OT1}% don't use the OT1 def any longer
%    \end{macrocode}
%
%    \begin{macrocode}
\DeclareTextSymbolDefault{\textperthousand}{TS1}
\UndeclareTextCommand{\textperthousand}{T1} % don't use the T1 def
%    \end{macrocode}
%    Using \cs{UndeclareTextCommand} above is enough only if the
%    encoding definition files are not reloaded afterwards. In the
%    past that happened if \texttt{fontenc} was used in the document
%    preamble (not any longer). So in some sense it is better to fully remove
%    them from the encoding files, but for rollbacks it is easier to
%    keep them in for now.
%
%    These are the standard \texttt{itemize} and footnote symbols
%    originally taken from \texttt{OMS} and now from \texttt{TS1}:
%    \begin{macrocode}
\DeclareTextSymbolDefault{\textasteriskcentered}{TS1}
\DeclareTextSymbolDefault{\textbullet}{TS1}
\DeclareTextSymbolDefault{\textdaggerdbl}{TS1}
\DeclareTextSymbolDefault{\textdagger}{TS1}
\DeclareTextSymbolDefault{\textparagraph}{TS1}
\DeclareTextSymbolDefault{\textperiodcentered}{TS1}
\DeclareTextSymbolDefault{\textsection}{TS1}
%    \end{macrocode}
%
%    And here are the other \texttt{TS1} glyphs that are implemented
%    by every font (or nearly every)---a few are commented out and
%    moved to sub-encoding 9,
%    because they aren't around in some fonts.
%    \begin{macrocode}
%%\DeclareTextSymbolDefault{\textbardbl}{TS1} % subst in sub-enc 9 above

%%\DeclareTextSymbolDefault{\texttwosuperior}{TS1} % subst in sub-enc 9 above
\DeclareTextSymbolDefault{\textyen}{TS1}
%    \end{macrocode}
%
%    \begin{macrocode}
\DeclareTextSymbolDefault{\textcapitalcompwordmark}{TS1}
\DeclareTextSymbolDefault{\textascendercompwordmark}{TS1}
%    \end{macrocode}
%
%
%    In the following sections the remaining default definitions are
%    ordered by sub-encoding in which they are become
%    \textbf{unavailable}, i.e., they are not provided in the
%    sub-encoding with that number and all sub-encodings with higher
%    numbers.
%
%    Thus the symbols that are available in sub-encoding $x$ are the
%    symbols above (always available) and the symbols listed as becoming
%    unavailable in sub-encodings $x+1$ and higher.
%
% \subsection{Unavailable in sub-encoding \texttt{1} and higher (drop symbols not working in
%    Latin Modern)}
%
%    The \cs{textcircled} is available but the glyph is simply too
%    small so we keep using the \texttt{OMS} glyph.
%    \begin{macrocode}
\DeclareTextCommandDefault{\textcircled}
  {\CheckEncodingSubset\UseTextAccent{TS1}{\UseTextAccent{OMS}}1\textcircled}
%    \end{macrocode}
%
%
%
%
%
% \subsection{Unavailable in sub-encoding \texttt{2}  (majority of new OTF fonts via autoinst) and higher}
%
%    \begin{macrocode}
\DeclareTextCommandDefault{\t}
  {\CheckEncodingSubset\UseTextAccent{TS1}{\UseTextAccent{OML}}2\t}
%    \end{macrocode}
%
%    Capital  accents are really only very seldom implemented, so from
%    sub-encoding \texttt{2} onwards we use the normal \texttt{T1}
%    accents if they are asked for in the document.
%
%    In Unicode engines we don't implement them at all but always use
%    the basic accents instead. whether that works or not really
%    depends on the font, something like \verb=\"X= usually comes out
%    wrong in Unicode engines.

%    and the slot is reused for random ligatures. So better not use it
%    because often it is wrong.  But pointing to TS1 is also not great
%    as only a few fonts have it as a real symbol, so we get a
%    substitution to CM or LM.
%
%    Alternatively we could just state that the symbol is unavailable in

% \subsection{Unavailable in sub-encoding \texttt{5} (most older PS fonts) and higher}
%
%    Most older PS fonts (supported in \TeX{} since the early nineties
%    when virtual fonts became available) are sorted under this
%    sub-encoding. But in reality, many of them don't have all glyphs
%    that should be available in sub-encoding \texttt{5}. Instead they
%    show little squares, i.e., they produce ``tofu'' if you are
%    unlucky.
%
%    But the coverage is so random that it is impossible to sort them
%    properly and if we tried to ensure that they only typeset those
%    glyphs that are really  always available, we would have to put them all into
%    sub-encoding \texttt{9}; so putting them into 5 is really a compromise.
%
%    Modern fonts usually don't typeset a tofu character if a glyph is
%    missing. They are therefore only classified as sub-encoding \texttt{5} if they
%    really support its glyph set completely.

% \section{Font family sub-encodings setup}
%
%    We declare the subsets for a good number of fonts in the kernel
%    \ldots
%
%    But first the default for anything that is not declared.  We use
%    \texttt{9} which is most likely much too conservative, but with the
%    advantage that we aren't getting missing glyphs (or at least that
%    this is very unlikely).
%    For nearly all font in the \TeX{} Live distribution of 2019
%    ``correct'' classifications are given below, so that this default
%    is only used for new font families, and over time the right
%    classifications can be added here too.

%    The lmtt family is missing TM, SM, and perthousand for some

%    Below are the newer fonts that have support files for
%    \LaTeX{}. With very few exceptions the classifications are done
%    so that all characters are correctly produced (either being
%    available in the font or substituted).
%
%    There are a few fonts that contain ``tofu'' squares in places
%    (instead of a real glyph) and in a few cases some really seldom
%    needed chars are unavailable, i.e., produce missing glyphs (to
%    avoid that a large number of available chars are unnecessarily
%    substituted).
%
%    Encoding declarations for these font families shouldn't really be
%    in the kernel, but part of the \texttt{.fd} files for the
%    family. When we introduced the concept in 2021 we had some hope
%    that this would happen over time and that we could take the
%    declarations out---after all it is nearly impossible to maintain
%    it correctly in the kernel, given that fonts may get new glyphs
%    added (happened for several of them in the recent year) which is
%    something we wouldn't notice. However, so far this hasn't
%    happened, so in 2024, I went through the current set and adjusted
%    the declarations in several places.
%
%    Next four are wrong and still need adjustment:

\NeedsTeXFormat{LaTeX2e}[2020/02/02]

%
%    This is implemented by defining the default subset:
%    \begin{macrocode}
\DeclareOption{full}{\DeclareEncodingSubset{TS1}{?}{0}}
\DeclareOption{almostfull}{\DeclareEncodingSubset{TS1}{?}{1}}
\DeclareOption{euro}{\DeclareEncodingSubset{TS1}{?}{8}}
\DeclareOption{safe}{\DeclareEncodingSubset{TS1}{?}{9}}
%    \end{macrocode}
%    The default is set up in the kernel is  ``safe'' these days for
%    unknown fonts but LaTeX has definitions for most families so it
%    seldom applies.
%
%    If a different default is used then one needs to check the
%    results to ensure that there aren't ``missing glyphs''.
%
%    The next set of options define the warning level (default in the
%    kernel is info only). Using the package options you can change this behavior.

%
%    The ``force'' option basically changes the sub-encoding  to that

% \subsection{The old textcomp package code}
%
%    This section contains the old code for the textcomp package and
%    its documentation. It is only used if we roll back prior to 2020.
%    Thus all the rest is mainly for historians. Note that the old
%    code categorized in the sub-encodings only into 6 classes not 10.
%
%    \begin{macrocode}
%<*TS1oldsty>
\ProvidesPackage{textcomp}
   [2018/08/11 v2.0j Standard LaTeX package]
%    \end{macrocode}
%
%    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.
%
%    Since many PostScript fonts only implement a subset of |TS1| many
%    commands only produce black blobs of ink. To resolve the
%    resulting problems a number of options have been introduced and
%    some code  has been developed to distinguish sub-encodings.
%
%    The sub-encodings have a numerical id and are defined as follows
%    for \texttt{TS1}:
% \begin{description}
%
% \item[\#5] those \texttt{TS1} symbols that are also in the ISO-Adobe
%       character set; without \verb=textcurrency=, which is often
%       misused for the Euro.  Older Type1 fonts from the non-\TeX{}
%       world provide only this subset.
%
% \item[\#4] = \#5 + \verb=\texteuro=.  Most newer fonts provide this.
%
% \item[\#3] = \#4 + \verb=\textomega=.  Can also be described as
%       $\texttt{TS1} \cap (\texttt{ISO-Adobe} \cup
%       \texttt{MacRoman})$.  (Except for the missing "currency".)

%
% \item[\#2] = \#3 + \verb=\textestimated= + \verb=\textcurrency=.  Can
%       also be described as $\texttt{TS1} \cap
%       \texttt{Adobe-Western-2}$.  This may be relevant for OpenType
%       fonts, which usually show the Adobe-Western-2 character set.
%
%    \item[\#1] = \texttt{TS1} without \verb=\textcircled= and \verb=\t=.
%       These two glyphs are often not implemented and if their kernel
%       defaults are changed commands like \verb=\copyright=
%       unnecessarily fail.
%
%    \item[\#0] = full \texttt{TS1}
% \end{description}
%
%    And here a summary to go in the transcript file:
%    \begin{macrocode}
\PackageInfo{textcomp}{Sub-encoding information:\MessageBreak
    \space\space 5 = only ISO-Adobe without
                              \string\textcurrency\MessageBreak
    \space\space 4 = 5 + \string\texteuro\MessageBreak
    \space\space 3 = 4 + \string\textohm\MessageBreak
    \space\space 2 = 3 + \noexpand\textestimated+

    \space\space 1 = TS1 - \noexpand\textcircled-

    See the documentation for details\@gobble}
%    \end{macrocode}
%
% \begin{macro}{\DeclareEncodingSubset}
%    An encoding subset to which a font family belongs is declared by
%    the command |\DeclareEncodingSubset| that takes the major encoding as the
%    first argument (e.g., |TS1|), the family name as the second
%    argument (e.g., |cmr|), and the subset encoding id as a third,
%    (e.g., |0| for |cmr|).
%
%    The default encoding subset to use when nothing is known about
%    the current font family is named |?|.
%    \begin{macrocode}
\def\DeclareEncodingSubset#1#2#3{%
   \@ifundefined{#1:#2}%

% \end{macro}
%
%
%  The options for the package are the following:
%    \begin{description}
%    \item[safe]
%       for unknown font families enables only symbols that are also
%       in the ISO-Adobe character set; without "currency", which is
%       often misused for the Euro.  Older Type1 fonts from the
%       non-TeX world provide only this subset.
%
%    \item[euro]
%       enables the ``safe'' symbols plus the |\texteuro|
%       command. Most newer fonts provide this.
%
%    \item[full] enables all |TS1| commands; useful only with fonts
%       like EC or CM bright.
%
%    \item[almostfull]
%       same as ``full'', except that |\textcircled|
%       and |\t| are \emph{not} redefined from their defaults to avoid
%       that commands like |\copyright| suddenly no longer work.
%
%    \item[force]
%       ignore all subset encoding definitions stored in the package
%       itself or in the configuration file and always use the default
%       subset as specified by one of the other options (seldom useful,
%       only dangerous).
%    \end{description}
%
% \begin{macro}{\iftc@forced}
%    Switch used to implement the \texttt{force} option
%    \begin{macrocode}
\newif\iftc@forced   \tc@forcedfalse
%    \end{macrocode}
% \end{macro}

%    This is implemented by defining the default subset:
%    \begin{macrocode}
\DeclareOption{full}{\DeclareEncodingSubset{TS1}{?}{0}}
\DeclareOption{almostfull}{\DeclareEncodingSubset{TS1}{?}{1}}
\DeclareOption{euro}{\DeclareEncodingSubset{TS1}{?}{4}}
\DeclareOption{safe}{\DeclareEncodingSubset{TS1}{?}{5}}
%    \end{macrocode}
%    The default is ``almostfull'' which means that old documents will
%    work except that |\textcircled| and |\t| will use the kernel
%    defaults (with the advantage that this also works if the current
%    font, as often the case, doesn't implement these glyphs).
%
%    The ``force'' option simply sets the switch to true.
%    \begin{macrocode}
\DeclareOption{force}{\tc@forcedtrue}
%    \end{macrocode}
%
%    The suggestions to user is to use the ``safe'' option always
%    unless that balks in which case they could switch to
%    ``almostfull'' but then better check their output manually.
%
%    \begin{macrocode}
\def\tc@errorwarn{\PackageError}

%    \end{macrocode}
%
%
%
%
% \begin{macro}{\CheckEncodingSubset}
%    The command |\CheckEncodingSubset| will check if the current font
%    family has the right encoding subset to typeset a certain
%    command. It takes five arguments as follows:
%    first argument is either |\UseTextSymbol|, |\UseTextAccent|
%    depending on whether or not the symbol is a text symbol or a text
%    accent.

%    The second argument is the encoding from which this symbol should
%    be fetched.
%
%    The third argument is either a fake accessor command or an error
%    message. the code in that argument (if ever executed) receives
%    two arguments: |#2| and |#5| of |\CheckEncodingSubset|.
%
%    Argument four is the subset encoding id to test against: if this
%    value is higher than the subset id of the current font family
%    then we typeset the symbol, i.e., execute |#1{#2}#5| otherwise
%    it runs |#3#5|, e.g., to produce an error message or fake the
%    glyph somehow.
%
%    Argument five is the symbol or accent command that is being
%    checked.
%
%    For usage examples see definitions below.
%    \begin{macrocode}
\iftc@forced
%    \end{macrocode}
%    If the ``force'' option was given we always use the default for
%    testing against.

  \else
   \expandafter\@secondoftwo
 \fi
  {#1{#2}}{#3}%
  #5%
}
%    \end{macrocode}
%
%    In normal circumstances the test is a bit more complicated: first
%    check if there exists a macro
%    |\|\meta{arg2}|:|\meta{current-family} and if so use that value
%    to test against, otherwise use the default to test against.

%    The |\textcircled| and |\t| are handled specially, unless the

%    Finally input the encoding-specific definitions for

%    \begin{macrocode}
\input{ts1enc.def}
%    \end{macrocode}
%    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. 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}
\UndeclareTextCommand{\textdollar}  {OT1}
%    \end{macrocode}
%    Similar declarations should probably be made for other encodings
%    like \texttt{OT4} if they are in use.
%    \begin{macrocode}
%\UndeclareTextCommand{\textsterling}{OT4}
%\UndeclareTextCommand{\textdollar}  {OT4}
%    \end{macrocode}
%    From the \texttt{T1} encoding there are two candidates for removal:
%    \textperthousand{} and \textpertenthousand{} since these 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
%    improvement over just getting a single `\rule{3pt}{3pt}' to
%    indicate a completely missing glyph, which would happen if we
%    also `undeclared' |\textpertenthousand|.

%    This is a simple file that asks for a name of a font family and

%    and recommends the right encoding subset (to be used with
%    \cs{DeclareEncodingsubset}) for this family.

%
%    For the purpose of this check a glyph exists if the font slot is
%    occupied---too bad if that contains the wrong glyph or some tofu.
%    If it ``exists'' we return 0 otherwise 1. This way we can call
%    this macro several times in a row and obtain a number that is 0
%    if all glyphs are existing or greater than 0 if any of them is
%    missing.
%
%    The second argument (holding the command name for a symbol) is
%    not used during these tests.

%
%    This macro also tests and outputs some information about the

%    as the code is concerned, the
%    symbols that are supposed to be always available (the core)
%    become available if we test the group \texttt{-1} and \texttt{0}.
%
%    The first argument contains the testing code and is supposed to

%    If some glyphs are missing, we rerun the test code but this time

%    \begin{macrocode}

%
%    If a font family is not found when declaring it with
%    \cs{DeclareFixedFont} we end up with the following font. This can

%    Then we start testing the groups beginning with the glyphs
