The ncurses build doesn't support double lines (they get converted to single lines), and doesn't support other strange line drawing characters one might experiment with (they get converted to replacement letters), including (but not limited to):

• double horizontal, single vertical corner: ╒ (U+2552)
• thick corner: ┏ (U+250F)
• rounded corner: ╭ (U+256D)

In a graphical terminal with UTF-8 support, there shouldn't be a reason not to support any Unicode character. The slang build is able to display any of these without problems.

In #2165 comment 10 andrew_b expressed his concerns about moving the single/double lines stuff from skins to the engine because it kills creativity. I wanted to be creative and create a skin where the horizontal lines are double lines and the vertical ones are single ones. With ncurses it just doesn't work. Currently only single lines are supported by the ncurses build.
