(Little does OP know, the characters are not limited to ascii.)

Most of these characters aren't ascii

So I decided to figure out what this actually is, since it's certainly not ASCII.
It's definitely not all of Unicode. I see a lot of glyphs that could be ANSI drawing, and I think
there's a lot of Cyrillic in there as well. I see nothing from any CJK language. I see very few
accented letters, but ё is present.
In each frame, there are about 54 lines, with about 125 characters per line. To figure out the
approximate size of this encoding: In the first frame, there are about 17 newlines. In another
random frame (I think the 7th), there are also 17 newlines. Assuming the data displayed is
completely random, that gives us a disturbingly nice estimate of 400 characters total in the set.
That's wrong, though, because newlines and tabs take up more space than a single character. The
tabs aren't uniformly 8 characters, but rather they seem to be be interpreted as “advance to the
next tabstop”, so we'll say they are, on average, 4 spaces wide. Assuming 20 tabs and newlines
per page (inflating a bit from 17 because newlines at the edge of the frame are less visible, so
I probably undercounted), and that the newlines are distributed horizontally following a uniform
distribution, we have an estimate of
(54 * 125) - (20 * 4) - (20 * 125/2) = 5420 characters per screen,
giving an estimate of 280 characters in the set. That sounds an awful lot like 256 (or at least,
far better than 400), so let's go with that.
That cuts it down quite a bit. The 256 character limit doesn't help, but it definitely rules out
multibyte encodings, and enforces that we're probably looking at something with 8 bits to a
character (so we're NOT looking at DEC Radix-50 or any of the pages for 36-bit machines).
In fact, if I had to guess, I'd say it's probably CP866 (https://en.wikipedia.org/wiki/Code_page_8
66). I've stared at screenshots and at that page for a while, and I've bee able to find just
about every CP866 glyph in my screenshot, and they seem to match to me.

Looks a lot like when you cat /dev/urandom in a terminal on a unix-like OS
