Apple provides a copyrighted image for U+1F600 GRINNING FACE. Google also provides a copyrighted image for U+1F600 GRINNING FACE. And so on.

If you want to use Apple's image for U+1F600, your use either has to be “fair use” or Apple has to grant you a license. For example, Apple's app store guidelines explicitly grant you the following license:

> 4.5.6 Apps may use Unicode characters that render as Apple emoji in their app and app metadata. Apple emoji may not be used on other platforms or embedded directly in your app binary.

And of course because it's Apple, enforcement is capricious: https://www.theverge.com/2018/2/8/16992830/apple-emoji-crack...

So you might want an image for U+1F600 which you are clearly licensed to use. OpenMoji is one source for such an image.
