And it's not ASCII, it's CP437.
Well, I prefer the term "ANSI-like", which I acknowledge is not exactly accurately named, but reflects the Codepage 437 heritage
and the dynamic/colourful nature of the display. I used to hand-code some (simple, and not particularly good[1]) ANSI movies back at Uni on the old terminals we had then, and later on messed about a bit with them in a later job when I came back across it (and ANSI.SYS for the DOS machines) when I was
actually supposed to be setting up printer control headers to prepend to various text files to make the old dot matrix printers change resolution/page dimensions/etc for various reports. (No, I didn't need/use ANSI with the printers, but I think it was a useful diversion that most of the time looked like I was working on what I should have been.
)
So, anyway, thus my tendency to talk about ANSI-like. Or "ANSII-like" if I don't stop my fingers doubling up that 'I', which is so easily done, given the spelling of ASCII and the mechanics the bouncing up off of the shift key seemingly doing something to the nervous system in the other half of my body on such occasions!
