Sadly enough, Office 2008 and Chinese don't play at all well together. As you probably know, the new versions of Office (for Windows and OS X) use Microsoft's new Open XML file type, making the file extensions be docx, pptx, xlsx, etc. Being that I'm taking a Chinese class where the teacher has Office 2003, the teacher often sends us (the students) "legacy" Word documents and PowerPoint presentations to help us review or to assign as homework. However, since I upgraded to Office 2008, it seems that the Chinese characters get garbled. TextEdit to the rescue! TextEdit is finally becoming somewhat of a real word processing application with tables, fonts, styles, links, lists, and even a ruler! The first TextEdits didn't really have all that. Anyway, I've included a screenshot of the same document in Word 2008 and TextEdit, and I plan to send a bug report to Microsoft.
I got my dock on the right using TinkerTool, in case you like it.
