Ok, now I have read that one can change the encoding in the terminal
to get same table drawing characters (if one does not want to use
unicode).
But such a question: can one do it programmaticaly?
And more important: can one use binary (bitmap) fonts in default modern
linux console? If yes, can one patch them with custom tiles at
the application start?
In DOS, (I don't remember if in all versions or only some)
one could do all this and this opens very rich possibilities for
approximating of objects with tiles. The only limitations
that one uses 255 tiles, but even this enables to build
whole 'worlds' and state of the art apps. So I would call this
pseudographics and not few sticks and corner tiles
(which I cannot even define and upload easily).
