CHAR_USE will attach the two fonts at addresses font1 and font2 to the window in place of the current system fonts.
When a character is printed, if it cannot be found at either font1 or font2, then the first character of the second font will be used.
To return to the current system fonts on the specified window, use font1=0 or font2=0 as appropriate.
If you use the value of -1 as one of the parameters, then that font attached to the specified channel will not be altered by this command.
