That was my initial thought too on seeing the title, having never heard the term before. So I decided to look it up and it turns out there is a whole separate genre called “ANSI art” based on a different tech stack and a naming mistake from history:

- ASCII is a real ANSI standard, the 7-bit character set that we all know and love

- Microsoft, IBM and others extended this to many different 8-bit sets, each with its own “extended” characters in the 128-255 range, often including both graphic symbols and control codes

- one of the more popular ones, windows-1252, became informally known as ANSI because Microsoft hoped that this (and others) would become new ANSI standards (they didn’t)

- people on BBSes and then early websites used this encoding standard to create art using graphic symbols and colour codes that are not available in ASCII art

- due to the optimistic, but ultimately incorrect, naming of both charset and the supporting library, this became known as ANSI art
