Besides the FIDE standard (or short) algebraic notation (SAN) already described, several similar systems are in use for their own particular advantages. Figurine algebraic notation (or FAN) is a widely used variation of algebraic notation which substitutes a piece symbol for the letter representing a piece, for example: ♞c6 in place of Nc6. (Pawns are unlabeled, just like in regular algebraic notation.) This enables moves to be read independent of language. The Unicode Miscellaneous Symbols set includes all the symbols necessary for FAN.
