In the computer industry, a dingbat font or pi font is a computer font that has symbols and shapes located at the code points normally designated for alphabetical or numeric characters. This practice was necessitated by the limited number of code points available in 20th century operating systems.

A dingbat is a glyph that is not a letter, number, or form of punctuation. Most dingbats are pictograms: simple graphical representations contained in a typeface, borrowing characteristics from the main characters.
