5.2.2 Features determined at compile time

When the Guile-Ncurses library was compiled, tests were run to see which features could be enabled. There are two variables that describe the capabilities of this build of Guile-Ncurses.

Constant: %wide-ncurses

This is set to #t if Guile-Ncurses is using the features of the wide ncurses library libncursesw. Otherwise, it is #f.

Constant: %ucs4-chars

This is set to #t if Guile-Ncurses expects that characters are stored as UCS4 codepoints, such as in Guile 2.0.x. It is #f if Guile-Ncurses expects that characters are 8-bit only and stored according to the current 8-bit locale.
