Probably don't care.

I have no idea what "randoseru" means, or what kind of backpack it is. Looking it up, it seems to be a design that carries special meaning in Japan, and not really anywhere else. While other countries _may_ have similar designs, it's not something special to them.

Even if the emoji looked like a ranoseru backpack, it wouldn't mean anything to most people. If anything, the front pocket is more likely to be associated with a backpack used for school.
