I still have most of the 437 code points memorised. At one point, I made a simple program similar to xxd or od but which would dump the binary code ones in (Unicode) 437 representation instead of just dots. (NUL, space, and 0xFF are all blanks, so I used other Unicode code points for those.) A little bit similar to Base-437 above.
Hey I love the sound of that! Please publish it on GitHub so I can build it in C or whatever. I think it was the blanks in xxd that gave me the idea for how good it would be to just display them - Unicode!
I’ll have to dig it up and put it out there for you. It’s actually already on GitHub but buried in another completely unrelated repo (networking tools where I was looking at undecoded binary dumps of network traffic).
