Convert unscii_8 font

Continuing the discussion from Bdf font since v6.0:

I am trying to convert unscii_8 font to add some additional symbols.
I use online converter.
The problem is that symbols of my font are not displayed at all.
Result font has negative base_line value. But base_line has uint8_t type in lvgl library. So negative value transforms to big value.
As a result, check in lv_draw_basic.c, line 291: pos_y + g.box_h < mask_p->y1 failed.
How can i get result, similar to built-in font unscii_8.
And one more: what is exactly font do you use (there are also tall, thins, etc.)?
P.S. I test my app in simulator. Lvgl version is up to 2020.01.30.
my settings:

@puzrin Can you take a look at this? Should base_line also be signed?

I’ve just tried it and font was converter correctly. I’ve changed the uint8_t base_line to int8_t and now it works for me. I’ve pushed the fix to master.
