Whether a terminal returns 7 or 8 significant bits initially depends on the control mode of the terminal driver. The meta() function forces the number of bits to be returned by getch(3XCURSES) to be 7 (if bf is FALSE) or 8 (if bf is TRUE).
If the program handling the data can only pass 7-bit characters or strips the 8th bit, 8 bits cannot be handled.
If the terminfo capabilities smm (meta_on) and rmm (meta_off) are defined for the terminal, smm is sent to the terminal when meta(win, TRUE) is called, and rmm is sent when meta(win, FALSE) is called.
This function is useful when extending the non-text command set in applications where the META key is used.
On success, the meta() function returns OK. Otherwise, it returns ERR.
