%   \begin{abstract}
%     This package is the second step for \LaTeX-internally bridging the gap
%     between the Unicode and the TIPA package. The first step was the package
%     \href{https://www.ctan.org/pkg/unitipa}{\pkg{unitipa}}. Users can now use
%     their beloved TIPA shortcuts with the benefits of Unicode i.e.\
%     searchability, copy-pasting, changing the font and many more. As this
%     package needs the package \pkg{fontspec} for loading an IPA font, it needs
%     to be compiled with Lua/\XeLaTeX. This package can also be viewed as an
%     ASCII-based input method for producing IPA characters in Unicode.
%   \end{abstract}
%   
%   \section{Acknowledgements}
%   
%   This package is completed because of the rigorous help by Jairo A.\ del Rio,
%   Jonathan P.\ Spratte, Phelype Oleinink \textit{\&} Ulrike Fischer. Their
%   suggestions and contributions are extremely valuable for the development of
%   this package.
%   
%   Jonathan P.\ Spratte has helped the package by building a parser based on
%   \pkg{expl3}. Phelype Oleinik has helped the package by building a test-suit
%   for regression-tests. The tests can be seen in the git-repository of the
%   project.
%
%   Lemures Lemniscati pointed a few bugs in the documentation \& the code.
%   Their details are as follows.

%
%   Anja Hasse pointed a bug in the package with an SE question\footnote{%
%     URL: \url{https://tex.stackexchange.com/q/662466}%
%   }. It got fixed in v0.6.1 of the package.
%   
%   All of these contributions are highly valuable for the development of this
%   package.
%   
%   \section{Package options}
%   
%   \begin{function}{documentfont}
%     \begin{syntax}
%       documentfont=\meta{font-name}
%     \end{syntax}
%     
%     The default font for the entire document set by this package used to be
%     \href{https://ctan.org/pkg/charissil}{Charis SIL}. From |v0.7| the package
%     has changed the default font to \href{https://ctan.org/pkg/newcm}{New
%     Computer Modern}. The reason for this breaking change is that Charis SIL
%     was just used because of it's good support for IPA which was absent with
%     the default Latin Modern shape. New Computer Modern has developed all the
%     support for IPA \& hence I am making this change. Users can easily change
%     the default font with the package-option \verb|documentfont| as documented
%     below.
%     
% \begin{verbatim}
% \usepackage[documentfont=DoulosSIL]{tipauni}
% \end{verbatim}
%     
%     Please note that you must provide a value to this key. If you pass it an
%     empty value; i.e.,
%     \enquote{\verb|documentfont=\{\}|}/\enquote{\verb|documentfont=|} or no
%     value, i.e., \enquote{\verb|documentfont|}, you will be prompted with
%     errors from package \pkg{tipauni}. If an empty/no-value
%     \verb|documentfont| is used \& no other non-empty \verb|documentfont| has
%     been used so far; then the document is typeset with the default
%     font-family of Lua/\XeLaTeX, i.e., the Latin Modern family. If another
%     \verb|documentfont| has a non-empty value, the value of that option will
%     be used as the font of the document.
%   \end{function}
%   
%   \begin{function}{fontspecoptions}
%     \begin{syntax}
%       fontspecoptions=\meta{font-options}
%     \end{syntax}
%     
%     This option can be used to set options to the font set with
%     \verb|documentfont| package option. If the \verb|recommendedfont| option
%     is used \& has the highest priority; the options set with
%     \verb|fontspecoptions| will be used with the default font. If the
%     \verb|preservefont| option has the highest priority, this parameter will
%     be ineffective \& throw a warning. In the argument of this option write as
%     if you are writing in the optional parameter of the \cs{setmainfont}
%     command, e.g.:
%     
% \begin{verbatim}
% \usepackage[fontspecoptions={Scale=1.5}]{tipauni}
% \end{verbatim}
%     
%     \noindent If this options is used with no value it will be ignored with a
%     warning.
%     
%     \noindent E.g.\ Try \verb|\usepackage[fontspecoptions]{tipauni}|.
%     
%     \medskip
%
%     \noindent If it is used with an empty value it will reset the fontspec-options so
%     far you have set, e.g., Try:
%     
% \begin{verbatim}
% \usepackage[%
%   fontspecoptions={Scale=1.5},%
%   fontspecfontspecoptions={}%
% ]{tipauni}
% \end{verbatim}
%   \end{function}
%   
%   Please note that the keys so far documented are the only keys which take
%   values. Other than these the following keys \emph{don't} take any value. You
%   will be prompted with an error from package \pkg{expkv} if you use values
%   for the following keys.
%   
%   \begin{function}{preservefont}
%     This option will omit executing the \cs{setmainfont} command with New
%     Computer Modern. The typeset document will use the default font of
%     Lua/\XeLaTeX, i.e., the Latin Modern.
%   \end{function}
%   
%   \begin{function}{recommendedfont}
%     This option is used to override other font definitions made with option
%     \verb|documentfont|. New Computer Modern will be used as the main font of
%     the document when this option is used.
%   \end{function}
%   
%   Please note that every option so far mentioned can potentially override each
%   other, e.g., If a \verb|documentfont| is added after a \verb|preservefont|,
%   the former will override the latter (\& vice versa). It is true for all
%   these three package options.
%   
%   \begin{function}{resetfontspecoptions}
%     This option resets all the \pkg{fontspec}-options set with package option
%     \verb|fontspecoptions|. As noted for the font-options, these two options
%     which deal with the options of the loaded fonts also can override each
%     other. The last one loaded will be considered of the highest priority.
%   \end{function}
%   
%   \begin{function}{incompatible}
%     By default \pkg{\tipauniname} will throw a warning if symbols not
%     contained in the \pkg{tipa} package were used. Using this option you can
%     switch this check off if you don't have to stay compatible with
%     \pkg{tipa} to silence this warning.
%   \end{function}
%   
%   \section{List of available commands}
%   TIPA has two alternative methods for inputting IPA characters. In the
%   following tables, \textbf{Input A} column lists all the long TIPA commands
%   (e.g., \verb|\textrtailt|) \textit{\&} \textbf{Input B} column lists the
%   short ones (e.g., \verb|\textipa{\:t}|)\footnote{All of these commands must
%   be enclosed in the \texttt{\textbackslash textipa}
%   command. (e.g., \texttt{\textbackslash textipa\{\textbackslash :tP\}} for
%   {\ipa [ʈʔ]})}. This documentation lists down all the commands necessary for
%   typing symbols in the IPA chart.
%

%   \begin{ThreePartTable}
%     \begin{TableNotes}
%     \item[\textcolor{red}{§}] These commands are also available without
%       package \pkg{tipa}.
%     \item[1] \label{1} A symbol for this sound was introduced in 2005. The
%       last update of the package \pkg{tipa} was in 2004, so this character
%       is missing in it. A command for it is provided by this package. Such
%       \pkg{tipauni}-exclusive commands are written with red color in this
%       documentation.

% As can be seen above, everytime when a command that is absent in the
% \pkg{tipa} package is provided, it sets the conditional \verb|nontipa| to true
% value. At the end of the document this package checks if there is any instance
% of a non-TIPA command. If yes, it generates a warning in the .log file saying
% that this code is now incompatible with the TIPA package and some characters
% might be displayed with a different font. All of this is achieved with the
% help of following commands. The discussion on
% \href{https://topanswers.xyz/tex?q=1735}{this} question helped a lot for fine
% tuning the warning message.
