Can you load and use your own fonts on the Nook?
And have you already browsed this subforum? When I remember right you're not the first asking because of books in Arab.
In theory it is possible with the Pocketbook readers. They have a special Arab firmware and they allow for using custom fonts. But there are some problems with it, too. Maybe you can browse the Pocketbook subforum, too.

Edit: Has the attachment some resemblences with how it should look like? It is a screenshot from my Pocketbook.
