Despite:

$ sudo apt install libncursesw5 libncursesw5-dev

window.box(' ', "\u2500")

outputs a horizontal block of gray text instead of a nice horizontal box line.

What steps are needed to display wide unicode characters using the curses gem?

I can confirm the version of ruby does properly output the unicode I expect:

 puts "\u2500"*9
─────────

box doesn't support multibyte characters. Try the following code to check multibyte support:

Curses.init_screen
Curses.addstr("\u2500" * 9 + "\nEnter: ")
Curses.getch
Curses.close_screen

That worked for my needs - thanks!
