Wanna convert hex values of emojis into NSStrings so you can render them to the screen? Hahhahaha... YES!

-(NSString *)hexToString:(NSString *)hex {
    NSScanner *scan = [[NSScanner alloc] initWithString:hex];
    unsigned int val;
    [scan scanHexInt:&val];
    char cc[4];
    cc[3] = (val >> 0) & 0xFF;
    cc[2] = (val >> 8) & 0xFF;
    cc[1] = (val >> 16) & 0xFF;
    cc[0] = (val >> 24) & 0xFF;
    NSString *s = [[NSString alloc]
                   initWithBytes:cc
                   length:4
                   encoding:NSUTF32StringEncoding];
    return s;
}

// example usage
// controller.body = [NSString stringWithFormat:@"emojis => %@%@", [self hexToString:@"1F449"], [self hexToString:@"1F448"]];
