Two of my teachers gave me .doc files for something or another, and both of these files have a strange problem I've never seen before: Microsoft Word Viewer has apparently decided that it doesn't know what to do with certain text elements, and so it decides to display them in the MaplePi font. This is a greek letter font that comes with Maple, a program for creating math documents. As you might imagine, I do not particularly enjoy seeing a document in all greek text. I have no idea what font it's supposed to be using. I don't know anything about what the document is supposed to be. All I know is that if I open the document in OpenOffice.org, it appears in Arial Rounded MT Bold. What could possibly be going on? Why is Microsoft Word Viewer trying to display a document in a font like MaplePi (which isn't even a built-in font!)? Oh, and yes I've checked my region settings. No, my computer does not think I live in ancient Greece. I have Microsoft Office Word Viewer (11.8328.8329) SP3.
