How to add font style for the xlf translation template.

We created a rtf template in English version, then translated to different language version, e. .g .Chinese ....,  we hope to use specific font for the Chinese version, but not sure the best way to do it. We do not want to create additional template again. Only need the Chinese translation version.

I have added the new fonts and could find the font mapping under the template property, we know how to use the new Chinese font on the Template file or exporting to xlf file, but only want to modify the xlf Chinese version only as it translated from the English rtf template.
