Custom Font with some ascii char missing into simulator

I was setting up different size of the same font using BMFONT sw. I noticed that into the simulator the char % (37) was missing showing the empty square. I tried a simple debug and i also noticed that in the smaller size the % was missing but not in the other sizes. Anyway i uploaded the watchface and i noticed that on my real Fenix 5X pro the char % is visible!

I noticed also that in the simulator, using the smaller font, char 7 wasnt complete and the vertical line of the 7 was missing. Obviusly not into the real device!
