Search Category With Unicode Name When Posting

I am current running a Vietnamese forum ( and as of right now we cannot search for categories with Vietnamese names when posting, for example: Thông Báo (Announcement). Other non-unicode categories show up just fine.

As our forum has a lot of categories, it would be helpful to be able to do that.

Or is there a setting that I am not aware?

Thank you.
