Developer Panic has decided to not sell version 2.5 of its Apple Design Award-winning Coda Web development app in the Mac App Store, citing the difficulty of working with Apple’s sandboxing requirements. Apple began requiring apps submitted to, or updated on, the Mac App Store to be sandboxed as of 1 June 2012, forcing many developers to pull their apps from the store, stop updating them, or remove features to comply with the requirements. 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.
