Many sophisticated word processors like Microsoft Word or Open Office Writer support the skill to correct kern or the character spacing. In a well-kerned font, the two-dimensional blank spaces between each pair of characters all have a visually similar area. For example, when the characters A and V are placed next to each other, they can take up less total space if they overlap. This is because the right part of the A and the left part of the V fit together.
