Icon Request: Copyleft Symbol Icon
### Acknowledgement

- [X] I have searched through both open and closed issues and confirm that this icon has not been requested earlier.

### Icon

There's this unicode character that doesn't work in many devices which would be a nice adition to the copywrite icons - 🄯

### Name suggestion

Copyleft

### Use-case

For example, using it on a footer with 🄯 Copyleft 2021 instead of © Copyright 2021, which copyright is also a symbol of fork awesome, the opposite of it would be a great adition, no?
