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. > > > Another point, as I could understand PCB only accepts lines for the > > fonts, do not accept arcs.

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. > The font stuff only really happens in two places now - where it's read > in in file.c and where it's drawn in draw.c.

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.
