I really appreciate when authors like Kaoru Mori do their homework and show us things from other cultures accurately. Me being an arab, I can tell 'cause a lot of people get it wrong and write scribbles that LOOKS like arabic and/or arrange the letters from left to right (when it should be the other way around). Sure, google translate can help but it really shows when you use that (that's not even including the culture norms and traditions)
