It will use either UTF-8 characters or the ACS characters from TERM.
The way it decides which is somewhat confusing and it looks like it is
choosing to use UTF-8 even when I wouldn't expect it to so I'm not sure
it is actually working correctly in our ncurses version.
I don't think UTF-8 line drawing works properly, at least with the DRM
wscons.
What do you have in TERM now? Can you see if the borders are OK with
"TERM=xterm snake"? This seems to use ACS rather than UTF-8. If it does
I'll see if I can figure out why it choosing UTF-8 borders for the
others.
You can run it in script(1) to see what it is using for the border (lots
of 'q' or 'x' means ACS).
