When a word in single quotes falls at the end of the quotation, LaTeX decides to render it as "' instead of '". For example:

```
``He said it was `off the hook'''

```

would render: "He said it was 'off the hook"' (I don't know if the font will make that noticeable or not). Any workarounds?

Moreover, there is no difference between `'{}''` and `''{}'`, so I'm starting to suspect a package conflict or something.

For reference, my header is:

```
\documentclass[letterpaper,10pt]{article}
\usepackage[utf8x]{inputenc}
\usepackage{fullpage}
\usepackage[margin=.5in]{geometry}
%\usepackage{csquotes} % This worked, but can it be done without loading a package?
%\enquote{He said it was \enquote{off the hook}} 
\usepackage{fontspec}
\setmainfont[Ligatures=TeX]{DejaVu Sans}
\begin{document}

```
