pangram

A pangram or holoalphabetic sentence is a sentence using every letter of a given alphabet at least once.

The best-known English pangram is β€œThe quick brown fox jumps over the lazy dog”. It has been used since at least the late 19th century, was utilized by Western Union to test Telex/TWX data communication equipment for accuracy and reliability, and is now used by a number of computer programs (most notably the font viewer built into Microsoft Windows) to display computer fonts.
