using Microsoft JhengHei font for localization

I have developed course which has to localize in traditional chines. I have used default font on system which is  Microsoft JhengHei .

My problem is when publish the course, some words look thine in compare to others. Client have noticed this and asking me to resolve the issue.

It would be nice if some buddy provide me some solution or give me reason if could not be resolved.
