Annie's code name in this operation, "Helvetica" is widely known as the name of a popular sans-serif type font originally designed by Swiss typography company Haas for use on signs. Originally called "Neue Haas Grotesk", it was renamed after "Confederatio Helvetica", the Latin name for Switzerland (whence comes the use of "CH" as the international two-letter code for the country).
