Hello everyone,
I wasn't expecting much of traffic here, so as DNSB highlighted I've replaced the initial fonts with Arabic supported ones and it's working as expected. I modified version 1 due to some font comparability and the current version tested.
Here is couple of images from my eReader (The title font is not included in the KoboRoot file)
Today I noticed that the KoboRoot adds an extra keyboard layout, that I'll have to look at.
