Surprised to see the author suggest that the C64 keyboard did not include the graphics glyphs on the keys.
Both the VIC-20 and the C64 both had them, albeit printed on the front vertical face instead of the horizontal face like the PET.
Moreover, the VIC-20 and the C64 keys include the box glyphs as well so you could see what character you’d get via CTRL and the ‘C=‘ (“Commodore”) key.
The Wikipedia page* states PETSCII includes 192 characters, but the author seems to suggest it’s at most a 7-bit charset. I was a little surprised to find that out after reading the article.

Fun walk down memory lane.
