How can I output a smile face in C-Language with XCode

Question

Now I make the for statements as follow,

for (int i = 0; i < 256; i ++) {
            printf("%5c", i);
 }

And I want to get the real content with ASCII

I hope you know that ascii does not contain a single smile face character. So what is the actual content you want to output. The basic version of a smiley in ascii would be `:-)` or `:)`. I think there is a character from japan that looks like a smiley. In some fonts you also have smileys as a character. Any other smileys are done by showing icons instead of characters. — ikrabbe, Jul 06 '15 at 09:24

Those are MS-DOS OEM characters. The particular output depends on your terminal. Under Windows, run from the default command prompt, I indeed get "smile faces" (and lots of other characters) from your code, so I don't see the problem. — Jongware, Jul 06 '15 at 10:18

Provided your terminal is set to UTF-8 encoding, this piece of code

#include <stdio.h>

int main()
{
 char s[] = { 0xf0, 0x9f, 0x98, 0x8e, 0 };

 printf("%s", s);
}

To find out how to encode other UNICODE characters use the top navigation bar on the page (or the previous/next angle brackets)

You can try to use Unicode instead of ASCII

This's an example on Swift

let dog = String(UnicodeScalar(0x1F436))
println(dog)

for codeUnit in dog.utf8 {
    print("\(codeUnit) ")
}

Thanks, but I want do it in C-Language – Zhi Chang Jul 06 '15 at 09:43
I'm not sure about C-language, but you can use this itf8 codes of smile for input: 240 159 144 182. Actually I think it's impossible use Unicode symbols in program is written by C – Tikhonov Aleksandr Jul 06 '15 at 10:02

@TikhonovAlexander: uh, *what*? I have been doing the impossible for some years, then. Even if you mean one cannot use *literal* Unicode characters, well, that may depend on the compiler. See e.g. [Unicode encoding for string literals in C++11](http://stackoverflow.com/q/6796157/2564301) – Jongware Jul 06 '15 at 10:23
@Jongware yeas I meant it – Tikhonov Aleksandr Jul 06 '15 at 10:36
