Question

I have a NSDictionary created with data from a web api.

Here is the dictionary logged:

{
chapter =     {
    text = "\n  \tAmo\U00cc\U0081s";
};

}

When loging [dict objectForKey:@"chapter"] looks like this:

{
text = "\n  \tAmo\U00cc\U0081s";

}

And when logging [dict objectForKey:@"text"] I get

AmoÌs

which is not correct, it should be Amo\U00cc\U0081s / Amós

It seems to be an encoding problem, but I can’t figure it out.
Any idea why this is happening?

Thanks

The NSLog is printing correctly!!!

You can not print Unicode text to log. You have new line, a tab and \U00cc and \U0081 which is converting to some un-readalbe texts.

This is not a bug. CF and Cocoa interpret %S and %C differently from how printf and its cousins interpret them. CF and Cocoa treat the character(s) as UTF-16, whereas printf (presumably) treats them as UTF-32.

The CF/Cocoa interpretation is more useful when working with Core Services, as some APIs (such as the File Manager) will hand you text as an array of UniChars, not a CFString; as long as you null-terminate that array, you can use it with %S to print the string.
