How to add UTF-8 characters to an NSString?

I need to make chemistry formulas (SO4^2-), and the easiest way to make subscripts and superscripts seems to be adding UTF-8 characters, since KCTSuperscriptAttributeName: property of NSAttributedString doesn't work.

Is it possible for me to make an nsstring with normal characters and utf-8 characters?

Thanks

Justin's answer is good but I think what you might really be looking for is NSAttributedString (documentation linked for you) or NSMutableAttributedString, where you can add superscripts, subscripts, and other character styles that NSString by itself can't handle.

Take a look at other NSAttributedString questions here or via Google, like this potentially related question or this one.

Hope this helps you out!

According to NSString Reference "NSString is implemented to represent an array of Unicode characters, in other words, a text string."

It would be convenient to write as below: NSString* myStr = @"Any Unicode Character You Want";

Just make sure that your default text encoding is unicode.

yes. i assume you know the normal approach to make an NSString - here's one method to create an NSString from a utf8 string: -[NSString initWithUTF8String:].
