The 'em dash' (—) is a character that signifies a break in a sentence or description. It is the equivalent of a double hyphen which marks the end of a thought or a break in a sentence. The 'em dash' is longer than the 'en-dash' which in turn is long than the dash (hyphen), being the shortest of the three.
