In general, you should never rely on -description for output, since it's intended for debugging and may change between OS releases. In this case, NSDictionary and NSArray appear to be printing an old-style ASCII property list (NSPropertyListOpenStepFormat), which must use escapes for non-ASCII characters.
I need a real unicode character instead of '\U....' for a 'real' stdout in any NSString encoding but not in the given one (see my example).
You'll need to iterate the collections and print the contents yourself, or convert to XML using NSPropertyListSerialization and print that. If you need a specific encoding, use [[NSFileHandle fileHandleWithStandardOutput] writeData:[aString dataUsingEncoding:]].
