If this is the real system prompt, there's a mistake. The first "korean -->" in the following should be "japanese -->":

  If you are generating text in korean, chinese, OR japanese, you MUST use the following built-in UnicodeCIDFont. [...]
        - korean --> HeiseiMin-W3 or HeiseiKakuGo-W5
        - simplified chinese --> STSong-Light
        - traditional chinese --> MSung-Light
        - korean --> HYSMyeongJo-Medium
