swung dash n : a punctuation mark used in text to indicate the omission of a word
swung dashA {character} similar to {tilde} but appearing in the same vertical position as a {dash}, i.e. half way up rather than at the top like tilde. {ASCII} does not include a swung dash so tilde is used instead. It is commonly used for "approximates" or "is approximately equal to". (1997-06-28)
