    I have expressed various non-text items as characters at various times.

    Maybe one of them would be suitable for your demonstration.

    Each of them uses code points in the Private Use Area.

    A vector graphics system, eutocode graphics.

    A font format, the eutofont font format.

    A portable interpretable object code for a virtual computing machine.

    If none of the above is suitable for your purposes, then the Private Use Area is available for you to define a system of your own.
