ouch. If it's unknown, then you don't know the size. It could be an emoji (2 cells) or some pua stuff (anyone's guess).
Ncurses prints PUA characters without any problem, even though their wcwidth() is negative.
If ncurses doesn't know the width, it'll get confused when it repaints the screen. I don't know how to solve that problem.
When the user indicates they want to see all code points -- also the unknown ones -- then they accept that things may not be accurately displayed. Also, whenever an unknown code point is encountered and the user wants it to be displayed anyway, maybe disable the movement- optimizing routines with a call to redrawwin()?
putenv("ALLOW_UNASSIGNED_CODEPOINTS=yeah");The name's kind of long, and doesn't begin with "NCURSES_"
It was just an example. How about "NCURSES_SHOW_ALL"? Benno
