Note: Because of its considerable size and the typographic compromises required to make such a font, Arial Unicode MS should be used only when you can't use multiple fonts tuned for different writing systems. For example, if you have multilingual data from many different writing systems in Microsoft Access, you can use Arial Unicode MS as the font to display the data tables, because Access can't accept many different fonts.
