I have text in Illustrator that are in Chinese, using 苹方-简 typeface. When I copy and paste the same text into Indesign, the text changes into new characters.

I know you need to expand the characters to use as vectors, but sometimes we need to change the text and go back and forth before finalizing. The question is why does it not do that for english text? I copy and paste between illustrator and indesign all the time, but this is the first time I've come across changing the text content completely.
