Smooth streaming japanese text

You can smooth stream japanese text by using the smoothStream function with streamText, and the following regex that splits either on words of japanese characters:

page.tsx
import { smoothStream, streamText } from 'ai';
const result = streamText({
model: yourModel,
prompt: 'Your prompt here',
experimental_transform: smoothStream({
chunking: /[\u3040-\u309F\u30A0-\u30FF]|\S+\s+/,
}),
});
