GNU Chess using Unicode chess characters to display a chess board in the terminal.

Chess symbols are part of Unicode. Instead of using images, one can represent chess pieces by symbols that are defined in the Unicode character set. This makes it possible to:

• Use figurine algebraic notation, which replaces the letter that stands for a piece by its symbol, e.g. ♘c6 instead of Nc6. This enables the moves to be read independent of language (the letter abbreviations of pieces in algebraic notation vary from language to language).
• Produce the symbols using a text editor or word processor rather than a graphics editor.

In order to display or print these symbols, a device must have one or more fonts with good Unicode support installed, and the document (Web page, word processor document, etc.) it is displaying must use one of these fonts.^[1]

Unicode version 12.0 has allocated a whole character block at 0x1FA00 for inclusion of extra chess piece representations. This standard points to several new characters being created in this block,^[2] including rotated pieces and neutral (neither white nor black) pieces.

Unicode code points and HTML

Traditional chess symbols are part of the Miscellaneous Symbols block. Alternate symbols to support, for example, fairy chess are defined in the Chess Symbols block.
