I am getting a string from an API that has anchor tags in it, so I am creating an NSAttributedString from it, and displaying it in a UITextView so I can support tappable links.
The problem is that the incoming string isn't valid HTML, so it has unescaped unicode characters in it. Things like:
While I could deal with those specific cases, I'm concerned about any other unicode characters that come in, that I don't currently know about.
Example:
NSString *fromAPI = @"Reagan \U2014 saying";
NSDictionary *options = @{NSDocumentTypeDocumentAttribute : NSHTMLTextDocumentType};
NSData *data = [fromAPI dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithData:data options:options documentAttributes:nil error:nil];
This renders in the UITextView as: 
How do I get it to render the em dash and other unicode properly?

Found it, it looks like HTML won't render unicode unless you add this into the <head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
