u8x8 fonts in asset packs

[GameLord2011]

Description of the feature you're suggesting.

I noticed that the u8x8 part of the u8g2 library in the firmware dependencies. I am experimenting with fonts, and a while ago I accidentally put a u8x8 font in my asset pack, and it caused a build error. Is it possible to add u8x8 fonts to asset packs, if so, how?

Anything else?

What file types are your fonts you have in the asset pack, and what are the steps leading to the build error? Are you not loading the asset pack onto the SD card?

Asset packs and flipper itself use u8g2 font format, it's a C file that the asset packer converts to a binary blob that u8g2 can understand. u8x8 is another format and not one u8g2 can use from what I know (from what I understand u8g2 and u8x8 are 2 parts of the same library that work differently), so even if the asset packer could convert such fonts it wouldn't work afaik.

@956MB, I am using a custom asset pack that I put in the asset packs folder, I added a folder called "Fonts," and in it I added a file called "primary.c," in it I put in a font section from the U8G2 library. Once I accidentally put a u8x8 font section in there, and built it using the Build update bundle [release]
And during the build it said:

I just did a new build becuase i dont have terminal logs

[GameLord2011]

Please do not ask for the og logs becuase I uninstalled Ubuntu wsl and (tried) to replace it w/ kali linux, and my pc bluescreened while installing kali, had to reinstall ubuntu
