UEFI applications rely on Unicode output capability, and might use that for drawing pseudo-graphical interfaces using Unicode defined box drawing characters.
Add a simple test to display the most basic box characters, which would need to be checked manually on the screen for correctness. To facilitate this, add a three second delay after the output at this point.
