Hello,
In your code you are using the same font (Normal Arial Unicode) file "ARIALUNI.ttf" to create all the open type font objects. If Arial Unicode supports bold, italic and bold italic you will find different .ttf files for each of those styles and you would need to use those in your code. To achieve your requirement, you have to obtain the actual font files that support italics. We are not familiar with any fonts that support italic Chinese characters.
Thanks,
