Has anybody else noticed responses randomly including bits of other languages like Arabic?

Edit: I've been informed this issue is over-posted, my bad. I first ran into this problem while doing some anthropological research the cheat way. When bits and pieces were in a script I didn't recognize, I figured these were highly-specific cultural terms that were hard to translate or even transliterate and the model had just given up. But when I asked, these were common terms like 'area' or 'cost.' Now I'm seeing it in other places, even across account
