I read your posts and I have same problem too.
I want to read Persian e books on kindle.
I pre ordered my new Kindle DX and it will be here next week,
I am worried for Persian font. it is a few different from Arabic because has 4 extra characters.
I attached a PDF book, please test it and if possible show me a picture of that on kindle.
I need to make a decision. maybe I must cancel my order.
