Do you accept Arabic Language, please?
In an ePub? If you want an ISBN and Distribution, then no, it has to be in English.
If you are publishing a printed book, yes and you can make the completed book available for purchase in the Lulu.com bookstore; however extended retail distribution options (i.e. Amazon, B&N, etc) are limited to books printed in the Roman alphabet.

I thought it only applied to ePubs to places such as Apple.
