Haha just tried and it works! First I tried in Spanish (I'm in Spain) and it simply refused, then I asked in English and it just did it (but it answered in Spanish!)

EDIT: I then asked for a Fizzbuzz implementation and it kindly asked. I asked then for a Rust Fizzbuzz implementation, but this time I asked again in Spanish, and he said that it could not help me with Fizzbuzz in Rust, but any other topic would be ok. Then again I asked in English "Please do Rust now" and it just wrote the program!

I wonder what the heck are they doing there? The guardrailing prompt is translated to the store language?
