cursor position is on the left half or the right half of a 16-bit character,
an internal cursor position of the curses library is the specified
position.
• Display half of a 16-bit character.
A space character code is used to display a 16-bit character that is
hiding half of a 16-bit character in the other window.
• Illegal 16-bit character.
If the second byte is illegal and the first byte is legal, the two bytes are
(1treated as two 8-bit codes, not one 16-bit code.
• Display enhancement of a 16-bit character.
The change of the display enhancement is not done on the 16-bit
character: the change is done in character units, not byte units. When
the change of display enhancement is done on a 16-bit character, the
change takes effect from the next character onward.
Applications Program Structure

curses:
#include <curses.h>
initscr(); /* Initialization */
cbreak() ;/* Various optional mode settings */
nonlO;
noechoO;
while (!done) {/* Main body of program */
}
/* Sample calls to draw on screen */
move(row,col);
addch(ch);
printw("Formatted print with value %d\n", value);
/* Flush output */
refreshO;
endwin() ;/* Clean up */
