U+2014 "—" Em Dash Unicode Character

U+2014 "—" Em Dash is a punctuation mark that represents a long dash used to create a strong break in a sentence, often indicating a pause, a shift in thought, or an interruption. It is longer than a hyphen or an en dash and is typically used without spaces on either side in English writing, though some style guides recommend spacing it for readability. The em dash's name comes from its historical width, which was once equal to the capital letter M in a given typeface. Common uses include setting off parenthetical phrases for emphasis, signaling an abrupt change in dialogue, or replacing commas, parentheses, or colons to add dramatic effect.
