Wikipedia In typography, a dingbat (sometimes more formally known as a printer's ornament or printer's character) is an ornament, character, or spacer used in typesetting, often employed for the creation of box frames (similar to box-drawing characters). The term continues to be used in the computer industry to describe fonts that have symbols and shapes in the positions designated for alphabetical or numeric characters.
Examples of characters included in Unicode (ITC Zapf Dingbats series 100 and others):

The advent of Unicode and the universal character set it provides allowed commonly used dingbats to be given their own character codes.
