The number parenthesis () scuh as (1) (2) etc disappear when compiled on xelatex/polyglossia. Adding space character inside the parenthesis is not a solution in my case. So need your help desperately.
MWE:
\documentclass[10pt,a4paper]{article}
\usepackage[quiet]{polyglossia}
\setmainlanguage{english}
\setotherlanguage{arabic}
\usepackage{geometry}
\geometry{hmargin={0.04in,0.04in}, vmargin={0.04in,0.03in}, paperwidth=81mm, paperheight=105mm}
\newfontfamily\arabicfont[Script=Arabic, Scale=0.8]{Tahoma}
\begin{document}
\centering
\textarabic{نتبينت (9) نتيسن}
% Parenthesis with number in it is ignored.
\begin{Arabic}
نتبينت (9) نتيسن
\end{Arabic}
% Parenthesis with number in it is ignored.
%However following works:
\begin{Arabic}
نتبينت ( 9 ) نتيسن
\end{Arabic}
\end{document}
