Re: Problem with NSFileManger directoryContentsAtPath

This has to do with non-printable characters in pathnames.  Each 
application can different how they visually represent these 
characters.  The terminal just replaces them with '?', the Finder 
might use a space.

When you have a path from NSFileManager, leave it as is in the 
NSString if you're going to pass it to other Foundation file manager 
APIs.  If you need a C string of the path for C APIs, you can use 
NSFileManager's fileSystemRepresentationWithPath: to get a properly 
encoded C string.  Also displayNameAtPath: can give you the proper 
representation for displaying the path to the user but may not work 
when passed to file system APIs.
