IMHO in this video the end result doesn't qualify as ASCII art - square letters in particular are a deal breaker to me.
It is still a cool shader that turns input into text, even if it doesn't have the ascii art vibe.

Note that e.g. PETSCII, while internally 8x8, would be displayed using non-square pixels[1] - also not resulting in square letters.
