Why not to follow the way used in non-UTF mc,
and use curses-like calls (translated to ncurses calls or emulated by 
slang calls in myslang.h)?

  I have made mc 4.6.1 with UTF patches compile and run when
  linked against ncrurses 5.4 by replacing
  SLsmg_write_nwchars by addnwstr.

Thus, it may be a good idea to use addnwstr as the wide character output 
routine, addnwstr being a ncurses call or a wrapper around SLsmg_write_nwchars
 (along the lines addch is implemented now).

       Sincerely, Michail
