 Wide characters are supported by default in NetBSD curses.  The same
 characters are defined for both narrow and wide ACS (the wide versions
 are unicode renditions of the narrow characters).  So no real difference
 there.

 The application should be able to add those characters using the wide
 character calls in curses.  So, yes, it should work but it is really an
 application thing not a curses library level thing.
 
 If you are wanting to extend the ACS character set it would make NetBSD
 curses non-standard and would require custom terminfo entries to support
 the extended character set *and* it would probably only work in wide
 mode.  I suspect the ACS characters defined map onto the vt100 DEC
 Special Graphics Character Set and have stayed that way ever since.
