If you encounter the following at a public service desk:
A student opens up a Word Doc in MS Office 2013. They expect the language to be in English, but it appears in symbols.
Chances are the original Doc was created on a different operating system’s version of Word. Or possibly a different version of Word. What’s happened is that when a font doesn’t exist in Word 2013, it seems to default to symbols (they look Greek to me, but I’m a filthy monolinguist). To the best of our brief research.
This example occurred today. The original doc was in Baskerville. In Word 2013, Baskerville Old Face exists, but not plain ole Baskerville.
At that point, highlight the text & switch it to a font native to Word 2013 & the original English will appear.
