Thanks.
But now I'm not sure there's a bug here. You evidently expect the
lines of the box-drawing characters to join without gaps, but I'm not
sure what this expectation is based on. For example, Emacs on
MS-Windows doesn't use FreeType, but with a completely different font
I see the gaps here as well. The fact that older versions of FreeType
produced different display doesn't yet mean that display was correct
and the current one isn't.
So I'm inclined to argue that there's no bug here. What am I missing?
