Previously my vim was acting so strangely when I built it using brew and was typing Persian and it was inserting question marks. To fix it I deleted the .vim folder and and also the .vimrc file and build the vim from scratch. So I got a fresh vim install, then I started to try the solutions Tony described, because what you said made me realise I was doing something different from you. So the problem I guess was vim not recognising the terminal. Now it's working great just like I expect it when I 'set termbidi' in the vimrc file. I couldn't make it work in the iTerm though which is not a bidi terminal. Sorry for taking you time again.

Indeed, full-bidi (e.g. displaying on the same line Arabic-script text
in RTL direction and Latin-script text in LTR) is not possible in Vim
alone, even if compiled with +rightleft and +arabic, it needs
cooperation of a full-bidi-capable terminal, and it needs to know that
the terminal can display full-bidi text (the latter is the /raison
d'être/ of the 'termbidi' option). When Vim is not running in a
full-bidi terminal, it can display all text in either LTR or RTL, even
both in /different/ windows displaying the same file, but not both in
the same window. I'm happy to know that you finally made it work.
