Arch Linux good Font config for persian language

all we need is to first install some good fonts then we build 2 persian fonts from AUR called iranian-sans and iranian-serif and use the config that comes next :

sudo pacman -S noto-fonts noto-fonts-cjk noto-fonts-emoji ttf-dejavu ttf-liberation ttf-inconsolata ttf-roboto-mono

and we use this config :

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "urn:fontconfig:fonts.dtd">
<fontconfig>
    <!-- arabic -->

        <test compare="contains" name="lang">
