Apple has announced that over 100 million apps have been downloaded from the Mac App Store in just under a year since the online store opened on 6 January 2011. The company did not break out the difference between free and paid apps, nor was the number of apps (beyond “thousands”) shared. Although inclusion in the Mac App Store is by no means a guarantee of sales success, it has proven to be a boon for many Mac developers. follow link
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.
