My recommendations are you get a pixel style font (you can find many here https://www.dafont.com/bitmap.php), and then if you're planning to use unity you can follow this tutorial ( https://pavcreations.com/pixel-perfect-fonts-in-unity-the-practical-guide/ ) on making it stay crisp (read: not anti-aliased). As for making sure it doesn't travel across pixel subdivisions, if the viewport is stretched, that's another matter.
