permalink with UTF-8 chinese characters display issue

Hi,
I’m currently having permalink in UTF-8 chinese and when I see the source page, I see this
<a href=”http://www.abc.com/video/%e7%88%b6%e8%88%87%e5%ad%90-%e7%ac%ac100%e9%9b%86/

it should be look like this
<a href=”http://www.abc.com/video/父與子-第100集/

it seems like on it’s way to mysql, it gets translated

and i think this is giving me problem when google indexing it, my rank is so low. I was wondering if someone could help me resolve this issue?

I have all my php files saved in UTF-8 without bom and my mysql server are all set to UTF-8
Thanks
