If a character in wstr is a tab, newline, carriage return or backspace, the cursor is moved appropriately within the window. A newline also does a clrtoeol before moving. Tabs are considered to be at every eighth column. If a character in wstr is another control character, it is drawn in the ^X notation. Calling win_wch after adding a control character (and moving to it, if necessary) does not return the control character, but instead returns a character in the ^-representation of the control character.
If the first character in the string is a nonspacing character, these functions will fail. XSI does not define what will happen if a nonspacing character follows a control character.
