For the character mapping on how to make the Jawi characters appear on screen, you can refer here
Say we have the following
%specifying class
\documentclass{article}
%calling arabtex package.. you may need to install texlive-lang-arab
\usepackage{arabtex}
\begin{document}
%initializing Jawi char map
\setmalay
%since Jawi does not need vocalization
\novocalize
\huge
%I leave it blank, except date for header
\title{ }
\author{}
\date{}
\maketitle
%This is Jawi mode
\\
%Now let’s see for Arab
\setarab
\fullvocalize
%This will enable transliteration, automatically!
\transtrue
\arabtrue
%Right to Left text will be append
\begin {RLtext}
al-salAm `alaykum\\
bismi al-ll_ahi al-rra.hm_ani al-rra.hImi
\end{RLtext}
\end{document}
Now let’s see the output!
