For what it is worth, I added Unicode support to the draw command for the next release. This way you can draw in a Unicode file using the standard Unicode box-drawing characters without having to depend on an ancient ascii Terminal font. This will ONLY works well if you are using a fixed-width Unicode font, of course.
This also allowed me to add a few more line drawing types (thin lines, rounded corners, dotted lines, thin dotted lines), and I added the ability to move the cursor around without drawing using Ctrl+cursor, so that you can pick up your pen if you need to.
