+ NCURSES_NO_UTF8_ACS
+ During initialization, the <STRONG>ncurses</STRONG> library checks for
+ special cases where VT100 line-drawing (and the cor-
+ responding alternate character set capabilities)
+ described in the terminfo are known to be missing.
+ Specifically, when running in a UTF-8 locale, the
+ Linux console emulator and the GNU screen program
+ ignore these. Ncurses checks the TERM environment
+ variable for these. For other special cases, you
+ should set this environment variable. Doing this
+ tells ncurses to use Unicode values which correspond
+ to the VT100 line-drawing glyphs. That works for the
+ special cases cited, and is likely to work for termi-
+ nal emulators.
+
+ When setting this variable, you should set it to a
+ nonzero value. Setting it to zero (or to a nonnum-
+ ber) disables the special check for Linux and screen.
