Peep is a 'hexeditor'-style native OSX app with the emphasis on text encoding. There are many different text encoding systems (ways of representing characters within a file) and a file doesn't necessarily know what encoding it's in. This can lead to frustrating problems when the file is opened, ie strange or foreign-looking characters. Peep is useful when programming, when experiencing text encoding problems or when you need to extract information from a file that you can't open otherwise. Allows you to view files in a 'hexeditor' style, inspect, access or sort out encoding problems and even edit individual bytes in hex, decimal or text.
