Custom in-game font - how?

[MarcusInVR]

So I found this post in an older thread: viewtopic.php?f=181&t=403567#p4769112

I got my hands on the contents in the Github etc., also have BMFont, ImageMagick. Now, the repo with the tools etc. is quite old, about nine years it seems. Still, I tried to follow these instructions to the best of my ability and somehow managed to acquire a .abc file for the font, and subsequently I also managed to acquire the dds file needed.

When I placed the files in the exact directory (did not pack, just loose files) nothing happened. The game continues to use the normal sans-serif font.

However, I did find interesting content having to do with the abc files, see this folder in the repo: https://github.com/hhrhhr/Lua-utils-for ... aster/docs. It seems to contain definitions for the abc files... but I am not sure how current this is or how to use these to generate a abc file myself by writing a small C or C++ tool.

The person that managed to create the Exo2 font also made it work, so I am wondering if anyone has other, more up to date instructions on how to replace the standard in-game font?

Much appreciated!

EDIT:
Looked at the file abc_x4_format.h in the Github repo linked above, and I think most of it is clear - just one thing is not: which character is which ASCII code in the structs that contain the character information. What am I missing? Or must characters always be in a certain order?

So after about 9 hours of constant experimenting (and almost getting it), I give up. I can generate the proper font files, but for some reason the space character (32) is ignored so that all words are written in one go without any spacing. Too bad.
