"ascii" for some means "anything textlike", so for example you may see roguelike game developers saying "nice ascii" in response to a screenshot full of CP437, Unicode, or text-like glyphs, all very much not ASCII. Some will get defensive when called out on this, claiming that CP437 is okay to call ascii because it's "extended ASCII" (nevermind the many different and conflicting extensions), or others point out that they do not have a better term for something textlike.

And in Win32, the term "ANSI" is used variously to refer to the current default non-UTF-16 character encoding, any non-UTF-16 character encoding, any non-MS-DOS, non-UTF-16 character encoding, and probably other things I've forgotten.

Ironically, one of the few things you can reliably say about any "ANSI" encoding in Windows is that it was never standardized by ANSI.
