Are the new Semantic Embeddings in CoreSpotlight multi-lingual?

After watching https://developer.apple.com/wwdc24/10131, I'm curious if the semantic embeddings used to provide the "search of meaning" with this new capability are encoded with multi-lingual embeddings?

In particular, if I have content that is mixed in Korean and English, can those be seamlessly indexed together and queries in one language (english) find relevant content that was offered to be indexed as Korean?

Are the new Semantic Embeddings in CoreSpotlight multi-lingual?
