ANSI - Virtual Curiosities

What is ANSI?

ANSI [ansi.org] stands for American National Standards Institute. It's an organization that "oversees standards and conformity assessment activities in the United States." Its name appears when you encounter something that follows an American standard, specially instead of an international one (which would be an ISO standard).

Below, the same label and button, but the button is blue, and a list of items appears under it. Utf-8 is on the list and appears selected in blue. — Notepad's encoding dropdown list button, closed (above) and opened after clicking (below).
