79 wrapping and special-character processing as follows:
88 The newly added spacing character is the base of the active complex character.
89 Subsequent non-spacing characters can be combined with this base
93 If \fIwch\fP refers to a non-spacing character,
94 it is appended to the active complex character,
98 The cursor is not advanced after adding a non-spacing character.
99 Subsequent calls to add non-spacing characters will update the same position.

329 The defaults specified for line-drawing characters apply in the POSIX locale.
337 HP-UX curses equates some of the \fBACS_\fP symbols
341 and other symbols which are not used for line-drawing.
343 X/Open Curses does not specify symbols for thick- or double-lines.
344 SVr4 curses implementations defined their line-drawing symbols in

353 line-drawing characters.
354 Existing implementations of Unix curses (AIX, HP-UX, Solaris)
355 use only the \fBacsc\fP character-mapping to provide this feature.
356 As a result, those implementations can only use single-byte line-drawing
366 In contrast, for the same cases, the line-drawing characters

420 and zero or more non-spacing characters
423 may hold one non-spacing character.
426 \fI\%ncurses\fP adds the non-spacing character to the active
438 library in its non-wide-character configuration.
