The check mark is a predominant affirmative symbol of convenience in the English-speaking world because of its instant and simple composition. In other language communities, there may be different conventions. It is common in Swedish and Norwegian schools for a to indicate that an answer is incorrect, while "R", from the Swedish or Norwegian , i.e., "correct", is used to indicate that an answer is correct. In Finnish, ✓ stands for , i.e., "wrong", due to its similarity to a slanted v. The opposite, "correct", is marked with \cdot \! / \! \cdot, a slanted vertical line emphasized with two dots (see also
commercial minus sign). In Japan, the
O mark is used instead of the check mark, and the X or ✓ mark are commonly used for wrong. In the Netherlands (and former Dutch colonies) the
flourish of approval (or
krul) is used for approving a section or sum. In
German-speaking countries, ✓ is used for “correct” or “done”, but not usually for ticking boxes, which are crossed instead. The opposite of ✓ is ƒ (short for
falsch “wrong”). ==Unicode==
