People will find a way to be insulted by anything these days. If this was presented in a way which was any way offensive, I'd maybe react to how certain parts of it is presented, but it's so very mundane.

It was the numbers back then, and they were changed a bit to fit into the western world, but I think arabs were happy about that, not outraged.
Whenever someone uses concepts from my culture the wrong way, I can't really do anything but laugh at it. Anyone with any form of knowledge about the subject will know how ridiculous it looks and laugh as well. But I appreciate seeing references to my own culture, and understand why people are using it without taking offense to how they are using it, unless it's in a clearly offensive way. Like how neo-nazis think nordic style runes have anything to do with fascism..
Written language belongs to everyone, and it's not like this set is any form of mockery. It's rather the opposite, since the author of the set says they enjoy the esthetics of it.
