Document Classes ⇒ Kaobook template

[rafighb]

Hi,
As a beginner using latex, I want to use a kaobook template in overleaf. The book template opens and compiles smoothly. But I'm going to use this template for a book which will be written in Kurdish and Persian. What should I do in order to write in Kurdish/Persian and use Unicode characters?

Here is the kaobook-template link:

Thank you in advance
