ASCII Character ~Equivalency sign - tilde
The tilde (/ˈtɪldeɪ, -di, -də, ˈtɪld/) ˜ or ~, is a grapheme with several uses. The name of the character came into English from Spanish, which in turn came from the Latin titulus, meaning "title" or "superscription". The first ASCII standard (X3.64-1963) did not have a tilde. Thus ISO 646 was born (and the ASCII standard updated to X3.64-1967), providing the tilde and other symbols as optional characters. The free-standing tilde is at code 126 in ASCII, where it was inherited into Unicode as U+007E.
