Hi Tmzl,
Thank you for updating us.
We couldn’t find any file in the provided file download URL. However, we suspect the Chinese characters are not rendered since Arial Unicode MS font might not be installed on your machine. Kindly install the fonts and try the conversion.
If you still reproduce the issue after installing the Arial Unicode MS font , then share us the issue reproducing file which will be helpful for us to provide prompt solution at the earliest.
Regards,
Abirami.
