How to show price of product which retrieve with help of SDKBOX IAP?

I have integrated SDKBOX IAP successfully in iOS as well as android.I got all items information in logs.
Now, I want to show my product’s price in my in app purchase screen which i got in this method

void updateIAP(const std::vector<sdkbox::Product>& products);

For example, I have shown it like this in one label:

 std::string text =_products[0].price.c_str();
   auto label1 = Label::createWithTTF(text, "fonts/Marker Felt.ttf", 24);
   label1->setPosition(Vec2(visibleSize.width/2 +100,visibleSize.height /2));

Now, Problem is all countries currency’s symbol are not available in font file so I got box instead of ₹ (Rupees Symbol).
How to solve this problem? any suggestions or solution will be helpful to me.

Not all currencies have their own symbol, just check out http://www.xe.com/symbols.php.
A way around it is to use the format YYY X, where YYY three letters currency code and X is the amount of money in YYY currency.
