  Sexual orientation and gender politics
  Since the 1970s, variations of gender symbols have been used to express sexual orientation and gender politics. Two interlocking male symbols (⚣) are used to represent gay men while two interlocking female symbols (⚢) are often used to represent lesbians. Two female and two male symbols interlocked represent bisexuality, while an interlocked female and male symbol (⚤) represents heterosexuality.
  The combined male-female symbol (⚦) is used to represent androgyne or transgender people; when additionally combined with the female (♀) and male (♂) symbols (⚧) it indicates gender inclusivity, though it is also used as a transgender symbol.
  The Mercury symbol (☿) and combined female/male symbol (⚥) have both been used to represent intersex people. A featureless circle (⚪︎), neuter symbol (⚲), and the Alchemical Symbol (🜬) are used to represent both asexuality and non-binary people.
  Since the 2000s, numerous variants of gender symbols have been introduced in the context of LGBT culture and politics. Some of these symbols have been adopted into Unicode (in the Miscellaneous Symbols block) beginning with version 4.1 in 2005.
