use_legacy_coding - override locale-encoding checks
#include <curses.h>
int use_legacy_coding(int level);
The use_legacy_coding function is an extension to the curses library.
It allows the caller to change the result of unctrl, and suppress
related checks within the library that would normally cause
nonprinting characters to be rendered in visible form. This affects
only 8-bit characters.
The level parameter controls the result:
0 the library functions normally, rendering nonprinting
characters as described in unctrl.
1 the library ignores isprintf for codes in the range
160-255.
2 the library ignores isprintf for codes in the range
128-255. It also modifies the output of unctrl, showing
codes in the range 128-159 as is.
If the screen has not been initialized, or the level parameter is out
of range, the function returns ERR. Otherwise, it returns the
previous level: 0, 1 or 2.
This routine is specific to ncurses. It was not supported on Version
7, BSD or System V implementations. It is recommended that any code
depending on ncurses extensions be conditioned using NCURSES_VERSION.
