Question

I have a slider for testing and I want the characters represented by the slider position to be shown in a text field. But my text field only shows A-Z and a-z when running my solution below. How can I get Unicode characters into my text field?

- (IBAction) doSlider: (id) sender
    {
        long long theNum = [sender intValue];
        NSString *vc_theString = [NSString stringWithFormat:@"%c", theNum];
        [charField      setStringValue:vc_theString2];
    }

Answer 1

%c is inherited from C and limited to an 8-bit range. You should use %C, which will read in the corresponding argument as a unichar.
