This character is a Other Symbol and is commonly used, that is, in no specific script.

The Wikipedia has the following information about this codepoint:
A checkerboard (American English) or chequerboard (British English; see spelling differences) is a game board of checkered pattern on which checkers (also known as English draughts) is played. Most commonly, it consists of 64 squares (8Γ8) of alternating dark and light color, typically green and buff (official tournaments), black and red (consumer commercial), or black and white (printed diagrams). An 8Γ8 checkerboard is used to play many other games, including chess, whereby it is known as a chessboard. Other rectangular square-tiled boards are also often called checkerboards. In The Netherlands, however, a dammenbord (checker board) has 10 rows and 10 columns for 100 squares in total (see article International draughts).
