Source for u8g2_font_5x8

[You69Man]

I want to do some small modifications on the font u8g2_font_5x8_tr.
I understand that I need the BDF source for this font to be able to make changes using the 'fony' tool.
From the font page I found that the BDF sources of the X11 fonts are hosted here https://gitlab.freedesktop.org/xorg/font, and I actually can find lots of different fonts here. But how can I find the one font that was the source for u8g2_font_5x8_tr? Is there any reference that can point me to the right source? Thanks a lot!
