NSStrings "containing_underscore_characters" are wrapped in quotation marks when set in NSMutableDictionary?

Question

I'm adding NSStrings to an NSMutableDictionary. Some strings contain an underscore, some do not:

NSMutableDictionary *testDict = [[NSMutableDictionary alloc] init];
[testDict setObject:@"_startWithUnderscore" forKey:@"firstKey"];
[testDict setObject:@"NoUnderscore" forKey:@"secondKey"];
[testDict setObject:@"underscores_in_middle" forKey:@"thirdKey"];
NSLog(@"%@", testDict);`

OUTPUT:

firstKey = "_startWithUnderscore"; //Note the added quotation marks!

secondKey = NoUnderscore; //No quotation marks.

thirdKey = "underscores_in_middle"; //Also gets quote marks.

Uh, what's going on here? Where are the quotation marks coming from?

Here you go. http://stackoverflow.com/q/7227163/491980 – EmptyStack Sep 02 '11 at 09:28 — EmptyStack, Sep 02 '11 at 09:28

if ([[testDict objectForKey:@"firstKey"] substringWithRange:NSMakeRange(0, 1)] isEqualToString:@"_"])
{
    NSLog(@"I guess the quotes are just things that NSLog prints, definitely not actually in the NSString.");
}
