I'm glad that worked for you.
I was just as excited as you when I first realised that I could have arabic on my device in much the same way.
I'm really busy at the moment with other projects, but once I get some free time... I'll try and make those recipes for you.
Keep on rocking the Calibre.
I wish some other people would help me to try and get more Arabic recipes on Calibre though, would be great to see more Arabic spring up in new updates.
