Chinese Characters not show on header, menu, and message title

Hi dear,

This theme is really good looking.

I have found a problem, which I can’t figure out what’s the problem. Think you might able to solve.

I try to apply on one of my Chinese Blog, it appears no showing Header, Menu, and Post titles. As long as those are Chinese Characters.(see this screen shot)

To confirm my doubt above, I tried on another English Blog, it works flawlessly…(here’s the screen shot)

Try to dive into codes but can’t get any hints. The source code of the page has the details, but it just can’t show on the page…

Maybe you can help?

Thanks.

Regards,
Nelson.
