I know there are different types of ASCII art. I call some text art.Then ANSI art, Japanese ASCII art and computer generated (scanned images which are not really art at all).
Others, like typewriter art, are pretty simple to figure out (made on a typewriter).
But, I have heard the terms new skool, old skool, and of course, being a spelling and grammar person, I have never really liked them. So, I do like 7-bit ASCII. Even though no one I know (personally versus online) will know what I’m talking about. But, they didn’t know before either.
Here is what I found from a post about the three ASCII art styles. Written by Carsten Cumbrowski aka Roy/SAC.
7 bit ASCII
“Original” is actually another good term for 7 bit ASCII’s. Another term would be: “true” ASCII’s, because ASCII, standing for “American Standard Code for Information Interchange” is always 7 bit, using only ASCII code 32 (space) to 126 (tilde ~) ).
Here is the US Charsset, starting with ASCII character 32 (space/blank) and ending with the ASCII character126 (tilde: ~).
The space character is represented by the white block at the beginning.
