Question

I’m not sure if they use an image or if it’s some kind of text transformation, but how does apple achieve the curly quote style found in Siri responses? When I attempt to recreate it with regular quotes I get just that, regular quotes.

Answer 1

It looks like they are using the UNICODE “Left Double Quotation” and “Right Double Quotation” marks — code point U+201C (“) and U+201D (”). You can embed them directly into your source (see wikipedia for how to type them).

bash$ cat foo.m
#include <Foundation/Foundation.h>
int
main() {
    NSLog(@"“%@”\n", @"Hello");
    return 0;
}
bash$ gcc foo.m -framework Foundation
bash$ ./a.out
“Hello”

You can embed them as UTF-8 sequences using hex escapes as well:

    NSLog(@"\xE2\x80\x9C%@\xE2\x80\x9D\n", @"Hello");
