Preventing line breaks in part of an NSAttributedString

Question

I am working on a UILabel which features large main text followed by smaller text that tells you who said it:

Answer 1

There is also word-joiner \u2060 character in Unicode which will prevent line break on its either side and is invisible. I used it to force word wrap when degree sign was part of word, so the whole word will stay on the same line, in iOS.

Objective-C:

text = [text stringByReplacingOccurrencesOfString:@"°" withString:@"\u2060°\u2060"];
