¯\_(ツ)_/¯*
Also, this specific example isn't ASCII art, it's some other encoding which I forgot the name of, Japanese characters, variable width (in bytes). Common for it to be drawn using Arial or a metric compatible font rather than any monospace.
Note that "ASCII" art also refers to 8-bit extensions of the encoding, where "oldskool ASCII art" means strictly the actual 7-bit set. Not to be confused with ANSI art, which is the same as ASCII but with ANSI control characters, like for changing color.
"text art" is what I usually call everything combined, including art on the Commodore systems, only very recently made possible with Unicode officially. Anyways, I don't really see any of it on the image...
