how to get VBA in Word to recognize Chinese Characters on an iMac computer

Question

I am trying to use VBA in Microsoft Word for iMac computer to automate some repetitive tasks on Word documents written in Chinese traditional characters; document names are also in Chinese characters; when I try to open document in VBA, it replaces characters in name with question marks. Found an article on Spreradsheet1.com that said VBA uses "ANSI code pages" to provide support for international ASCII characters. It gives instructions for Windows PCs to go to control panel, select Region, click Administrative Tab, click Change system locale , then select which language to use. I am working on an iMac computer, so need to know how to accomplish the same result on iMac. A book "VB and VBA in a Nutshell", published in 1998, says VB has used Unicode starting with version 4;
