I tried this:

.ar{
 direction: rtl;
 text-align: right;
 font-family: Cairo; // the arabic font we use
}

I'm not familiar with Arabic, but I can see two methods 1. you try to link to a ttf file in your filecabinet

<link name="brush-font" type="font" subtype="opentype" src="url to .ttf" bytes="2" />

using something like this ^ Or 2) you use

NotoSansArabic_Bold
NotoSansArabic_Regular

Tried both 😢

ouch ok haha, hmm, maybe try a different ttf file? sometimes not all the ttf files are compatible 😆

Will do
