How can i use a pixelfont in the level (not UI) without loosing "details"?

Hi there,
i’m still a beginner and i’m trying to make a simple pixel-2d-game as an educational project.
I wanted to add simple little dialogue texts to my character-blueprints.

The purple text is made with a .ttf font in the UI and is just there for reference, how the font should actually look. The brown/orange/whatever text is a text render, made with a distance field in a font material. To get the material i just duplicated and altered some default one.

My problem now is, that the font via distance field and text material is not longer pixel perfect as you can see. The edges of the pixels do not touch (as they should) and the complete text is just rounded. Is there any (hopefully easy) way to fix this?

Thanks for your help!
