I was helping my wife get going with her new (and first) Mac, and apparently Microsoft Office does not support third party fonts, like at all. No, I'm not joking, it's in their official documentation:
Third-party fonts are not directly supported in Microsoft Office for Mac applications. Some third-party fonts may work in one application and not in another. Other third-party fonts are installed in a “family.” A family usually consists of the third-party font itself together with some or all of its variations (bold, italic, and so forth). Sometimes, a font may be displayed in Microsoft Word, Microsoft PowerPoint, Microsoft Excel, or Microsoft Entourage, but you may be unable to use one of its variations, such as italic.
Please tell me if this is wrong, because this is insane. My wife has switched to Pages because that's a deal breaker.
