\section{Overview}
The `swung dash' (\swungdash) is a rare but very useful mark of punctuation used in typesetting dictionaries and reference works as a stand in to avoid repeating the defined term in examples or definitions, and thus to save space.  For example, a quoted example of the term `extraterritoriality' might save space by omitting repeating the long word:
\begin{quote}
	\swungdash, in this as in every other case, is a fiction only, for diplomatic envoys are in reality not without, but within, the territories of the receiving States. The term `\swungdash' is nevertheless valuable because it demonstrates clearly the fact that envoys must, in most respects, be treated as though they were not within the territory of the receiving States. \footnote{Sir H  Lauterpacht \textsc{qc} (ed) \textit{Oppenheim on International Law}, vol 1 (8\textsuperscript{th} edn, Longmans, Green \& C\textsuperscript{o} 1955),  793}
\end{quote}

Although the swung dash is included in Unicode  as \texttt{U+2053}, few typefaces include it.  This package turns a tilde in any given typeface into a swung dash of 1 \textsc{m} width, and then, using the \texttt{accsup} package, overwrites this extended tilde into the Unicode character so that it will be read as a swung dash.
\section{Usage}
In your preamble put:
\begin{minted}[
framesep=2mm,
baselinestretch=1.2,
bgcolor=LightGray,
fontsize=\footnotesize,
breaklines,
firstnumber=last
]
{latex}
\usepackage{swungdash}
\end{minted}

To typeset a swung dash, simply use the command:
\begin{minted}[
framesep=2mm,
baselinestretch=1.2,
bgcolor=LightGray,
fontsize=\footnotesize,
breaklines,
firstnumber=last
]
{latex}
\swungdash
\end{minted}
