#1)
I posted earlier about my struggle to get ncurses working with UTF-8
under linux, and I got it working by including and linking to ncursesw -- 
but
its working -- AFAICT -- without me adding the XOPEN define you
had mentioned. Do I need that XOPEN define?

#2)
I don't understand how line drawing characters (such as AC_VLINE, I
think) work with UTF-8? That is, I don't know what they could
expand to that would work, unless they (macros I assume) expand
to characters between 0 and 0x20 which are not otherwise used.
I've looked in the ncurses faq for UTF-8, but if the answer is there
I overlooked it :(


Cordially,
