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.

We don't want to add any unnecessary waiting times in the unit tests. If somebody wants to see the output, he can scroll up.
