Please add a better warning when a smart quote is encountered in Objective-C source. This can happen when copy-pasting code from blogs.

Rationale:

Smart quotes and straight quotes are fairly similar on screen, and can be hard to pick out. However, using smart quotes gives you a strange error message, seemingly unrelated to the smart quote.

Example:

        NSDateFormatter *UTCFormatter = [[NSDateFormatter alloc] init];
        UTCFormatter.timeZone = [NSTimeZone timeZoneWithName:@“UTC”];

I get:

        Unexpected @ in program.

I'd like:

        Found a string using smart quotes: @“UTC”.
        Fix to @"UTC"?

Added comment about C string to the radar

As follows:

Note that in pure C code, I get a different error. This one is a little better: 

char foo[] = “foo”;

I get: 

Expected expression.

Would like: 

Found smart quotes: “foo”
Fix to "foo"?
