Have my own C variant, slightly different charset

Maybe it gives you ideas? Can share my own work.

[tenox7]

yeah please share your ideas and software if possible!

the problem with ttyplot is that I want to have multiple lines on a single chart, this limits what characters can be plotted when they intersect

but perhaps if only single line is used, we could add more char types ?
