    If you've got some technical documentation reference of this terminal, it
    would be worth to give it as it will be used in technical documentations.

    What you suggest is something else: it's a proposal to encode technical
    characters similar to control images, or to glyphs of keys on a keyboard. It
    is not a script, but a handy collection of unique glyphs.

    In a similar technical domain, I don't know if the technical glyphs that are
    (were?) used on terminals for IBM MVS systems, are all encoded. I remember
    there was a sort of zig-zag arrow pointing to bottom left, as well as other
    symbols denoting the current state of the terminal, and a few others to
    denote editing operations in a screen mode: one had to mark a edited line
    with a symbol, and the terminal took care of remember where editing was
    allowed and performed, and once you had created a modified line, you pressed
    a "Send" key to get the screen updated with the new text after editing
    operations. This was more or less working in a way similar to the "vi"
    editor line-mode interface, except that it was screen-based rather than
