Huh? What you sent has --- rather than an em-dash. This is automatically translated to an em-dash in the output.

If you wish to actually insert an em-dash, – (actually this is an en-dash since the font doesn't have an em-dash), into the source document itself you'll have to save the document in something other than pure ASCII and then let LaTeX ``know'' what encoding you are using; e.g. saving as UTF-8 Unicode in TeXShop:

%%!TEX TS-program = pdflatex
%%!TEX encoding = UTF-8 Unicode
\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\begin{document}
ad ‹ asdas --- as asd and then — .
\end{document}
