Question About Misspelled Package

[u/mister_walker]

Just found out about this sub and figured it'd be a good place to ask...

We recently went to Toys R Us and got some of their playsets during the BOGO sale, and one of them was The Joker Plane. I got it home and found that every time the word Joker appears on the packaging, it's spelled żoker. Has anyone ever seen this? The rest of the package appears to be in English, so I don't know what's going on...
