thanks (I'm not sure how I overlooked it)

not time - I just didn't happen to think of it, since my focus has always
been on the ncurses library itself.

I've started working on this.  Mike Aubury pointed it out, and the past
few patches have been directed toward this.  At this point I'm using the
ncurses.c 'r' test, fixing the issues that prevent it from working (by
pasting a wide-character from dialog's UTF-8 demo into an input field).

There are some isolated things that I've seen which need attention - they're
bugs, but not on the thread I'm following.  For example (from my to-do list):

2004/3/6
        I noticed a problem in ncurses 'r'; typed in "abcdef^]" and a couple
        of back-arrows, then "123".  The "1" appeared on the end.  But that
        went away with my changes to paint the (INS) or (OVL) on the top
        right corner.  This glitch appears between ncurses 4.2 and 5.0, appears
        to be a form-bug which was exposed by edit_secure() logic in
        form_virtualize():
                set_field_back(me, A_REVERSE);

*       Solaris curses checks input characters for validity in 'r' test as
        I type them - not at the end.  So I can't type "abc123" in the first
        field.  Also the display glitch above doesn't happen.
