I dont mean in the sources, but in real life. I dont know exactly why, but its 
a good practice to draw lines (connections) using only 45 deg lines (I 
suppose thats because of the silkscreen process), so, I was thinking about if 
the letters should be 45 deg too for some (or the same) reason.

Are you thinking in implementing it (to PCB-HID)? If so, I will start 
designing a new set of fonts right now. If so, I will not lost work designing 
a new font now only using lines and another usign arcs too.

That rule is a gerber imposition, or the gerber format accepts ellipses? 
When using PCB to draw an arc (I mean, when routing a board) sometimes is 
really important to have a function to draw a part of an arc.
