Narrator doesn't repeat non-English characters

Not sure whether is this a problem of just my local computer or not but this does happen.

My game language isn't English. I opened Narrator the other day and typed some sentences mixed up with English alphabets and Chinese characters. The Narrator, however, only repeated English characters, ignored Chinese one.

I still think there's sth goes wrong with my local computer, not the game's issue instead. But I cannot solve this problem, I don't know what goes wrong…
