Standard ncurses library does not pass UTF-8 characters properly.
As widechar-enabled libsmartcols directly uses UTF-8 characters in
table.c, it is unusable in applications using ncurses (e. g. cfdisk).
Fail if widechar support is detected, ncurses is supported but
libncursesw is not found.
Example of mangled cfdisk output:
/dev/sda1 2048 4095999 4093952 2G 5 Extended
>> M-b~T~TM-b~T~@/dev/sda5 4096 4095999 4091904 2G
