I would say that the information that is published with emojis included in the newer UTF-8 standards seem to cover this. You can also have a look at Emojipedia[1] where there is a lot of information about each symbol. I believe there is a certain overlap between common icons and symbols used for emoji. There is also some information to be found in various icon style guides, se Google's[2] for instance [1](http://emojipedia.org/ http://emojipedia.org/) [2](https://material.google.com/style/icons.html https://material.google.com/style/icons.html)
