In which case don't try and handle multilingual text pay someone else, even if that's on fiverr.

But isn't that exactly what it's just telling you? The order is important and if you see this very simple pattern it's wrong.
If you read any latin character based language then you surely must be OK with the idea that glyphs can be distinct? Are there many people who exclusively read languages where the order of symbols is not important?

If the point is that dyslexia means some people can't see the difference then that's fair, I'd not come at it from that angle. I don't see any surprising pre-assumed knowledge in this IJ/JI distinction however.
Who can't tell these apart? I know literally no Arabic - these characters look very much like latin ones I and J, and it's just an order thing.
It seems like an excellent quick test to me to see if there's ordering problems.
