Subject: [PATCH] Patch by Robert Scheck <robert@fedoraproject.org> for iftop
 >= 0.17, which works around a PuTTY issue (doesn't honor vt100 line-drawing
 when in UTF-8 mode) to get sane lines drawn instead of letters. When using
 PuTTY in UTF-8 mode, you have to execute "NCURSES_NO_UTF8_ACS=1 iftop" in the
 future. Technically, relinking from curses to ncursesw is just half of the
 solution, calling setlocale() is the rest. For further information, please
 have a look to Red Hat Bugzilla, bug ID #546032:
