U+1F12F "🄯" Copyleft Symbol Unicode Character

U+1F12F "🄯" Copyleft Symbol is a typographic character used to indicate that a work is available for copying, modification, and redistribution by anyone, provided that all derivative works also remain free and are licensed under the same or equivalent terms. It is essentially a reversed version of the copyright symbol ©, created by computer programmer Rick Falkvinge as a visual marker for the copyleft licensing concept, which is most commonly associated with open source software and free content licenses such as the GNU General Public License. While it is not a formal legal symbol like © or ℗, it serves as an important cultural and ideological icon within the free culture and open source movements.
