It's bad enough already without further abusing the term. "ANSI" is a U.S. standards organization recognized by ISO (which is an international s.o.). American National Standard X3.64 specifies what people loosely call "ANSI terminal" behavior. X3.64 does not cover the IBM PC extensions for line- drawing characters and other character graphics. Note that DEC's VT100 terminal, perhaps the first implementation of X3.64, had already provided such characters as DEC-specific extensions beyond X3.64, but naturally IBM ignored existing practice and came up with their own incompatible extension for this. Thus, any faithful emulation of the VT100 will discard the high bit of the 8-bit bytes and not support IBM PC graphic extension characters. I don't know where the term "ANSI graphics" originated, but it's a horrible misnomer.
