Unscii – A set of bitmapped Unicode fonts based on classic system fonts
I found line-drawing characters to be so inconsistent in fonts that I implemented them directly in my terminal emulator’s rendering code.  For example, when I see a box-drawing symbol, I bypass the font completely and draw lines myself so that the result is guaranteed to align consistently with other cells and guaranteed to touch adjacent cells without any gaps from font layout engines.  It’s amazing how much nicer it can be when you do this.This font does remind me of a lot of other useful symbols though, beyond normal box-drawing sets.
