The alif is now correct, but there are still misplaced chars,
eg, the ha in the last word of:
----------------------
\documentclass{book}
\usepackage{fontspec}
\setmainfont[Script=Arabic]{FreeSerif}
\begin{document}
\pardir TRT
\textdir TRT
نشر {\textdir TLT 1234} بنقل الإشارات برهن
نشر 1234 بنقل الإشارات برهن
\end{document}
----------------------
Trying to found where the problem is, I've tested the following
with ConTeXt and it's the same:
----------------------
\starttext
\setupalign[r2l]
\definefont[arabicfont][FreeSerif*arabic]
% \setupdirections[bidi=global,method=default]
\arabicfont
نشر {\textdir TLT 1234} بنقل الإشارات برهن
نشر 1234 بنقل الإشارات برهن
\stoptext
-------------------------
At the moment I cannot investigate further. I've updated
my TeXLive2017 and it has stopped working :-(.
Javier (just dreaming of a merge of xetex and luatex...)
