Office ADD-INS for converting among Viet encodings in Word/Excel Viet Character Convert Office Pack is a set of Microsoft Office ADD-INS for Word and Excel that allows conversion of the characters within a document from one Viet enconding to another. Currently only VISCII, VPS, and Unicode encodings are supported. There is a separate add-in file for each application. These add-ins should work in Office 97 up to XP(2002). Office 95 and below are NOT supported because they do not have UNICODE support.
