Troubling glyphs

Question

To type arabic with the same keyboard layout I used to use on Windows 10, I've created a .mim file (key mapping file) and put it in /usr/share/m17n to make it work with ibus-m17n on Ubuntu 18.04 LTS based KDE Neon. Everything except the ornated parenthesis, normal parenthesis, braces, brackets and angle brackets works as I expect. Here's my tex document:

\documentclass{article}
\usepackage{harfload, fontspec, arabluatex}
\usepackage[a4paper, margin=1in]{geometry}
%\setmainfont{Kalpurush}[RawFeature={mode=harf}]
\newfontfamily\arabicfont[Script = Arabic]{Al Qalam Quran Majeed Web} 
\newcommand{\textarabic}[1]{\bgroup\textdir TRT\arabicfont #1\egroup}     % Arabic inside LTR
\newcommand{\n}[1]{\bgroup\textdir TLT #1\egroup}     % for digits inside Arabic text
\newcommand{\afootnote}[1]{\footnote{\textarabic{#1}}}     % Arabic footnotes
\newenvironment{Arabic}{\textdir TRT\pardir TRT\arabicfont}{}     % Arabic paragraph
\parindent 0pt
\begin{document}
    \textarabic{﴾وَصِيَّةً﴿ مِّنَ ٱللّٰه} \\
    \textarabic{(وَصِيَّةً) مِّنَ ٱللّٰه} \\ 
    \textarabic{\{وَصِيَّةً\} مِّنَ ٱللّٰه} \\
    \textarabic{[وَصِيَّةً] مِّنَ ٱللّٰه} \\
    \textarabic{<وَصِيَّةً> مِّنَ ٱللّٰه}   
\end{document}

Here's what I've got:

Is it a harflatex/lualatex problem or have I missed something in making my keyboard layout? here's how the mapping looks like:

;; It's an edited copy of "ar-kbd.mim" file.
(input-method ar phonetic)
(description "Arabic Phonetic (MS Windows).")
(title "ض")

(map
 (arabic
  ("`" "`")
  ("1" "١")
  .
  .
  .
  ("[" "[")
  ("]" "]")
  ("a" "ا")
  .
  .
  .
  ("\(" "\(")
  ("\)" "\)")
  .
  .
  .
  ("{" "{")
  ("}" "}")
  .
  .
  .
  ("<" "<")
  (">" ">")
  .
  .
  .
  ((G-9) "﴾")
  ((G-0) "﴿")
  .
  .
  .
  ((KP_Add) "+")
  ((KP_Subtract) "-")
  )
)

(state
 (init
  (arabic)))

I've added the output libreoffice profuced for anyone who knows how to fix those in libreoffice writer.

Answer 1

arabluatex gets it more or less right. For braces you should according to the documentation use \abraces, the ornamental parentheses are intentional not mirrored in Unicode:

\documentclass{article}
\usepackage{arabluatex}
\newfontfamily\arabicfont{Amiri}[Script = Arabic]
\begin{document}
    \arb{﴾وَصِيَّةً﴿ مِّنَ ٱللّٰه} \\
    \arb{(وَصِيَّةً) مِّنَ ٱللّٰه} \\
    \arb{\{وَصِيَّةً\} مِّنَ ٱللّٰه} \\
    \arb{\abraces{وَصِيَّة} مِّنَ ٱللّٰه} \\
    \arb{[وَصِيَّةً] مِّنَ ٱللّٰه} \\
    \arb{<وَصِيَّةً> مِّنَ ٱللٰه}
\end{document}

luahblatex with luaotfload 3.11 gets it right too (again with the exception of the ornamental parenthese, which are intentional not mirrored in Unicode):

\documentclass{article}
\usepackage{fontspec}
\newfontfamily\arabicfont{Amiri}[Script = Arabic,Renderer=Harfbuzz]
\newcommand{\textarabic}[1]{\bgroup\textdir TRT\arabicfont #1\egroup} 
\begin{document}
    \textarabic{﴾وَصِيَّةً﴿ مِّنَ ٱللّٰه} \\
    \textarabic{(وَصِيَّةً) مِّنَ ٱللّٰه} \\
    \textarabic{\{وَصِيَّةً\} مِّنَ ٱللّٰه} \\
    \textarabic{[وَصِيَّةً] مِّنَ ٱللّٰه} \\
    \textarabic{<وَصِيَّةً> مِّنَ ٱللٰه}
\end{document}

with standard luatex it fails, also as luaotfload/the fontloader ignores the bidi-mirrored feature, see https://github.com/u-fischer/luaotfload/issues/61

\documentclass{article}
\usepackage{fontspec}
\newfontfamily\arabicfont{Amiri}[Script = Arabic]
\newcommand{\textarabic}[1]{\bgroup\textdir TRT\arabicfont #1\egroup} 
\begin{document}
    \textarabic{﴾وَصِيَّةً﴿ مِّنَ ٱللّٰه} \\
    \textarabic{(وَصِيَّةً) مِّنَ ٱللّٰه} \\
    \textarabic{\{وَصِيَّةً\} مِّنَ ٱللّٰه} \\
    \textarabic{[وَصِيَّةً] مِّنَ ٱللّٰه} \\
    \textarabic{<وَصِيَّةً> مِّنَ ٱللٰه}
\end{document}

Answer 2

[Edited] [Note: this is not an answer, but a simple additional remark]

This works with standard luatex, but LRE, RLE, and PDF Characters (Pop Directional Formatting) have been used. However, most of the fonts print these marksluaotfload has them printed by default (see the screenshot below).

\documentclass{article}
\usepackage{fontspec}
\newfontfamily\arabicfont{Amiri}[Script = Arabic]
\begin{document}
\pardir TRT\textdir TRT\arabicfont\noindent
‪﴿‬وَصِيَّةً‪﴾‬ مِّنَ ٱللّٰه\\
‪)‬وَصِيَّةً‪(‬ مِّنَ ٱللّٰه\\
‪\}‬وَصِيَّةً‪\{‬ مِّنَ ٱللّٰه\\
‪]‬وَصِيَّةً‪[‬ مِّنَ ٱللّٰه\\
‪>‬وَصِيَّةً‪<‬ مِّنَ ٱللّٰه\\
\end{document}
