Microsoft's Zune music player has barely seen store shelves, but it's already taken so much flak that I'm starting to feel a little sorry for it. But only starting, and in my most recent MacNotables podcast with Andy Ihnatko and Chuck Joiner, we expressed our incredulity that Microsoft could have released such a collection of compromises, confusions, and crashes, all bundled into a plain brown package. I can't pretend you'll learn anything useful from this podcast (unless you need ammunition for your own Zune target practice), but we had a heck of a good time recording it, and I think you'll enjoy the result.
Is it a Unicode Font?
To determine if your font is Unicode-compliant, with all its characters coded and mapped correctly, choose the Font in any program (or in Font Book, set the preview area to Custom (Preview > Custom), and type Option-Shift-2.
If you get a euro character (a sort of uppercase C with two horizontal lines through its midsection), it's 99.9 percent certain the font is Unicode-compliant. If you get a graphic character that's gray rounded-rectangle frame with a euro character inside it, the font is definitely not Unicode-compliant. (The fact that the image has a euro sign in it is only coincidental: it's the image used for any missing currency sign.)
This assumes that you're using U.S. input keyboard, which is a little ironic when the euro symbol is the test. With the British keyboard, for instance, Option-2 produces the euro symbol if it's part of the font.
