Parentheses don't appear after the compilation

I have an Arabic text. When compiling using XeLaTeX and the Noto Naskh Arabic font I can't get the parentheses, instead I got rectangles.

An extract from the code:

\documentclass[14pt,a4paper]{book}
\usepackage{polyglossia}
\setdefaultlanguage{arabic}
\setotherlanguage{english}

• I'm assuming this is a font encoding problem. But it would be easier for us to debug if the problem persists even if you have \begin{document}()\end{document}. – Teepeemm Jun 13 '17 at 18:00
