I tried doing something similar a couple of years ago and gave up after running into the exact same issues in the post. It's really difficult to replicate proper halftoning on a computer screen without getting moiré patterns and weird artifacts because of PPI, aliasing, and other stuff. Beyond that, print and screens are just fundamentally different ways of rendering things.
Basically I extracted the emojis from my Mac's system font. From there I downscaled them to 64x64 pixels and made them grayscale.
With this set of images I experimented with a few different algorithms. I ended up settling for just a regular ordered dithering (Bayer). But! It still didn't look that good. So what I ended up doing was normalizing the darks and lights for each emoji. This was because some emojis are lighter and darker than others. I wanted to create a uniform appearance for all of them.
So the process was (1) get emojis. (2) downscale + grayscale. (3) normalize tone. (4) dither. (5) then upscale
