Putting quotation marks in TeX document

Question

Have to put double quotes mark for a sentence. I am using Xetex. For the input string ``The work'', the output is also ``The work'' whereas it should be “The work”. Below is the list of packages and languages I am using.

\usepackage{amssymb}
\usepackage{polyglossia}
\usepackage{amsmath}
\setdefaultlanguage{english} \setotherlanguage{sanskrit}
\usepackage{fontspec} \setmainfont{Times New Roman}
\newfontfamily\devanagarifont[Scale=MatchUppercase]{Mangal.TTF}
\newfontfamily\devtransl[Mapping=DevRom]{Times New Roman}
\usepackage{graphicx}

\begin{document}
``The work''
\end{document}

Answer 1

Add the Ligatures=TeX option:

\setmainfont[Ligatures=TeX]{Times New Roman}

After setting this option, fontspec takes care that several characters in the input, which should produce a special ligature glyph in the output, are printed in the correct way. Now `` and '' will become “ and ”, respectively. A further example, now also -- and --- will become the en dash – and the em dash —, respectively.
